truck starts the fuel pressure shows real good then it shuts off

I have a 1997 Ford F-150When truck starts the fuel pressure shows real good then when you hit the gas peddle it shuts off. They are both working fine until accelerator is pushed. Computer was tested and works fine. However no diagnostic codes are being shown.

Answer:

Fuel pressure should be 30 psi at idle and when accelerator is pressed it should rise to 40 psi. If the pressure drops instead of increasing :

1) a vacuum leak at fuel pressure regulator

2) failed fuel pressure regulator

3) failing fuel pump.

The windshield wipers keep stopping on me and I have to wiggle the small harness to get them to turn on

Wiper Motor Pulse Board

What you need to do is unplug the harness, remove the 3 screws on the back of the wiper motor assembly. Remove the "pulse board" ( this is what the harness plugs into) there are two small contact points that stick out and have grease around them . clean the dirty grease, bend the two contact tabs out a little and reinstall it and it will work just fine. Extremely common !!!! The other option is to order a new one from the dealer( do not buy re man/rebuilt from aftermarket place) . Removal of the wiper motor is not necessary.

Should I buy the New Chevy Volt?

Lets take a minute to see what the pros and cons are along with some common sense thinking. OK, so you are in the market to buy a new car. That's wonderful that the Media Scare on the economy hasn't worked on you. So lets use some numbers and base it on lets say MONEY!

The New Chevy Volt, 230 mpg, an Electric Plug-in that has a gasoline assist engine to charge the batteries on the go is said to Sticker Price at around $40,000.00 WOW!!!! and for arguments sake lets pick a lessor expensive New Car, will pick the Ford Focus that gets 35 mpg and Stickers around $15,000.

Lets say you spend $20.00 a week driving the New Ford Focus and $2.80 a week (electricity costs money too). It costs you $1040.00 a year in gas to drive the New Focus and $145.60 a year to Drive the New Volt.

Now lets do a little math. $40k - $15k = $25K ... hmmm $25k /$1040.00 per year = 24 years worth of gas.

So you would have to drive the New Chevy Volt 24 years in order to make up the difference of money you spent, not to mention that no one knows how long the Volt will last maintenance wise.

Now you might say , oh I am helping the environment! Did you know that electricity that is made by burning fossil fuels is pretty much the same thing??? So I am gonna have to say if you want to buy an electric hot-rod that is kinda cool looking, great get you a Chevy Volt and be happy but Don't think it is gonna help the environment or your wallet.

Air Conditioner Problems

Any automotive air conditioning system employs four basic parts-a mechanical compressor, driven by the vehicle's engine; an expansion valve, which is a restriction the compressor pumps against; and two heat exchangers, the evaporator and the condenser. In addition, there is the refrigerant that flows through this system. Avoid the need for an auto air conditioner service call Look Below for car auto air conditioning repair Troubleshooting Procedures

The freon is compressed and flows through the condenser where it is cooled into a liquid. The freon passes through the receiver/dryer to remove moisture. Once the freon leaves and enters the expansion valve/orifice tube The high pressure liquid becomes a vapor and is extremely cold as it passes through the evaporator and on to the compressor to repeat the cycle.

Air Conditioner blows warm air 1. Air conditioner system is discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary. 2. Air conditioner compressor clutch not engaging. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

Rough Idle ! 2000 Pontiac Sunfire

OK here we go........2000 Pontiac sunfire gt 2.4 litre engine 180 000 Km rough idle started suddenly one morning...... things I've tried and tested..... changed spark plugs twice replaced throttle body gasket replaced intake manifold gasket tried new coils checked engine compression all between 216-222 psi checked engine vacuum not steady but between 14-15" mercury added two cans combustion chamber cleaner no check engine soon light!!! my GM mechanic had it for three hours could not find anything added one can injector cleaner thing i haven't checked evap egr catalytic converter fuel pressure engine idles rough only, when it gets above 1500 rpm it disappears but it takes longer than usual to come back to idle speed , all this happens hot or cold....... Hope you can help or suggest............Rick Response: Your problem you say is below 1500 rpm and that the vehicle runs fine above 1500 rpm. I would say you need to replace the IAC valve (idle air control). The IAC only functions at or below 1500 rpm. This is a common issue with GM engines. If you have replaced the intake manifold gasket , this should be fairly simple for you. Also when you remove the old IAC clean any excessive carbon that may be present.

Cash For Clunkers Survives For Now

The U.S. Government is Spending your tax dollars on cars.... Still ! Are they trying to help Obama Motors or just see how much debt they can create. Time will tell.

Congress sent President Barack Obama legislation Thursday night with an additional $2 billion for "cash for clunkers," the economy-boosting rebate program that caught the fancy of car buyers and instantly increased sales for an auto industry long mired in recession.

The government said Wednesday that more than $775 million of the original funds had been spent, accounting for the sale of nearly 185,000 new vehicles. Administration officials estimate the extra funding will last into Labor Day. Under the program, passenger car owners are eligible for a voucher worth $3,500 if they trade in a vehicle getting 18 miles per gallon or less for a new car getting at least 22 mpg. Vouchers of $4,500 are available for owners who trade in a passenger car getting 18 mpg or less for a model that gets at least 28 mpg.

The longer-term impact of the program is less clear. "Once these clunker rebates expire, it is over," predicted economist Richard Yamarone of Argus Research. "Consumers are not going to keep buying cars. It is a temporary one-time gimmick, not a long-lasting tonic for the recovery."

In the program so far, GM's share of cars sold is largest, accounting for 18.7 percent of new sales. Toyota Motor Corp. followed with 17.9 percent, while Ford had 16 percent. Detroit automakers represented 45.3 percent of the total sales, while Toyota, Honda Motor Co. and Nissan Motor Co., all Japanese firms, totaled 36.5 percent.

Toyota also has the best-selling new model for traders of clunkers, the Corolla. The Ford Focus, Honda Civic, Toyota Prius and Toyota Camry are also favorites. There is one SUV on the list, the Ford Escape, which also comes in a hybrid model that can get up to 32 mpg. Six of the top-10 selling vehicles are built by foreign manufacturers, but most are built in North America.

a/c is blowing warm and my engine is overheating

my 2002 Hyundai Elantra a/c is blowing warm and my engine is overheating. The belts are all in place. there are no leaks of coolant on the ground. There are no noises coming from the water pump. Do you have any ideas what may be the problem? I ran over a deer a few weeks back on the interstate. The car has ran fine since, but I did sustain some damage around the radiator (braces got bent up). I am wondering if this problem has popped up after the fact. Answer: Most likely cause (since you hit a deer) would be that there is a hole in the A/C Condenser (Reference Diagram) that is located in front of the radiator. This would allow the freon to escape. As for the overheating, since some brackets were bent, etc. there is probably some damage that was done to the fan assembly not allowing the fan to function for the radiator. This would make it overheat. Another thing that would cause both issues would be air flow restriction. If there is deer fur stuck in the condenser and blocking air flow, neither the A/C system would work properly nor would it allow air to flow through the radiator also causing the engine to overheat.

p0720 code a put and output speed sensor on the car

what is the most likely cause for a p0720 code a put and output speed sensor on the car is a 2001 Suzuki SUV with a 4l30e the transmissions 1-2 shift is a late one shifts to second very late all other shifts seem good

Answer:

That is an output speed sensor problem. You need to have your output speed sensor replaced. This will cause the transmission to shift erratically due to it not knowing the correct speed of the vehicle. This is a pretty common problem with several vehicles.
