I have a 94 chevy truck 5.7 engine that turn over alot before it starts then sometimes will idle sometimes die, then when you start to drive away it takes the fuel then 3 seconds later boggs, take foot off pedal and push own again it reponds the same way. If you floor it then it will fly until it shifts to second then it starts the same thing over. It seems to be a fuel problem it acts identical to the older vehicles with a manual chock not pulled on a cold day. Thanks.

Hi Elmer, I'm glad to help! Elmer there are a lot of things that can cause a dieing problem. FIRST, see if it will stay running if you push the gas pedal a little bit then crank it. If it runs and stays running but dies when you release the pedal then here are a few things you can check. (1) You may have an "IDLE AIR CONTROL MOTOR" sticking and is stuck in the closed position. SOMETIMES this works, take sometime and tap on the motor and if it starts idling properly replace the motor. (2) You could possibly have a "THROTTLE POSITION SENSOR" that bad and does not signal the engine controller that the engine is at idle so it dies. If you can get it to idle then tap on the TPS when its bad it will idle the engine way up while tapping on it. If it does then replace the TPS. (3) You could also have a FAULTY or DIRTY "MASS AIR FLOW SENSOR" If the vehicle has one, some do some don't. If your vehicle is equipped with one, you can take it off and try cleaning the air flow sensor inside it. If it idles properly your good to go. If it doesn't idle properly I wouldn't rule out the sensor being bad. (4) You could possibly have a vacuum leak, vacuum leaks cause all kinds of crazy problems because it confuses the engine controller. If you can get it to idle, then you can take parts cleaner and spray around the intake manifold and if it dies right away then you have a vacuum leak that needs to be repaired. (5) You could have fuel issues, BUT, if the engine runs good while driving it down the road then you can rule this one out. These are the most common problems that occur and cause dieing problems. Hope this helps and have an awesome day Elmer.

I have 94 s 10..4.3 v6. it does the same thing have replaced fuel pump and filter,ignition module,cap rotor plugs wires,coil,ground strap...driving down the road jus dies like the key got shut off....for a while when troubleshooting through the parts you could get it to restart.....now when it dies it cranks really hard when trying to restart..ive checked the timeing its fine....if i wait a few min it will usually start...sometimes it will show a check engine light sometimes not......never know when it will happen sometimes jus down the the road from the house sometimes 100miles down the road......sometimes three times in a mile sometimes not for weeks at a time..Wtf...Im ready to shoot it like a lame horse....its a shame too its a sharp lil truck thats a two owner and never spent a night outside in its life...i knew the original owner ...i bought it with 90,000 on it it only has 148,000 now and still looks like new...

What engine ? 4.3 , 4.8 , 5.3 or 6.0 l What fuel injection system ? What is the fuel pressure ? Do you know what fuel trims are ? The fuel pressure regulator's are prone to leaking to leaking on thses SPI injection system./

no its more than likely not related to the trans,if you are having shift problems though,i would have the tps(throttle position sensor) checked out.another thing to check is the vacume lines to and from the egr valve and the valve its self for proper operation.

YEP COULD BE EGR VALVE STUCK OPEN BUT YOU WOULD GET CHECK ENGINE LIGHT WARNING.YOU COULD HAVE BAD GAS OR NEW REPLACE FUEL FILTER AND AIR FILTER CLEAN FUEL INJECTORS SEE IT THAT HELPS.

check your idle air control valve, when you turn the a/c on the idle air should increase to help keep engine stay idle.

check your vacuum lines they are weather cracked and leak vacuum air

YOU COULD HAVE A RESTRICTED AIR FILTER OR FUEL LINE OR FILTER.YOU COULD HAVE DEFECTIVE FUEL SUPPLY PUMP OR DEFECTIVE INJECTION PUMP.YOUR IDLE SPEED TOO LOW OR FAST IDLE INOPERATIVE.

check for a pluged cat converter

I had the same problem with my 94 chevy 6.5 diesel,and spent alot of money trying things that people told me to try.I wound up taking it to the dealer and they told me it was the injection pump.They put one in it and that fixed it.It has run great for over a year and a half.This set me back about $4000.00!
