Check to see if you have a flapper valve that operates your feul injection if you do you might have to replace it.

Out of the blue . truck looses power and wants to die. not letting it die by hitting gas peddle it runs but starts back firering supper bad. truck dies .starting up it doesnt want to put . made it home .....


if you have replaced cap and rotor plus coil and it seemed to fire up then i would take the next step. For sure put your new plugs and wires on then make sure you have replaced your air filter, and change out your fuel filter, fire up the vehicle if it doesn't start I would suggest changing the fuel pump. If it starts up make sure you put in some BK fuel injector cleaner in your fuel it might be you have dirty injectors. If all fails then get back with me and we will look else where. Good luck hope this info helps you out

Use a gage and check proper fuel pressure, with TBI, around 9--13 psi. There probably isn't a Schrader valve, to check fuel pressure tee into supply fuel line. Be aware of possible fuel pressure when taking fuel lines loose.

Car died and wont start


The fuel injector motor or called the Idle Air control module is not the failure. The fuel pump is overheating and dies out. Thus when letting sit a while the engine is starting up again.
I woult take vehicle to local shop and have them replace the fuel pump , I suggest not getting taken for a complete tune up. Just the fuel pump is the most cost effective way .

Fuel delivery problem


There usually is a strainer in the gas tank. After 23 years, anything is possible. If you have a carburetor, replace it, or have it cleaned. If fuel injected, the big hose from the air filter could be damaged and shifting loose. If the engine doesn't see the right vacuum, it won't work right. Check all the little vacuum lines. Get a vacuum gauge, learn how to use it. Do a fuel flow test to see if your tank is clogged.
