My friend has a 93 Suburban that wont start. we put new fuel pump and filter in it.
that didn't fix it. We have good fuel pressure to the throttle body but the injectors wont spray when trying to start . When we dump gas in the throttle body the truck will start and stay running as long as you have the gas peddle pushed more then half way. as soon as you let the peddle up, the injectors shut off and the truck dies. I have no idea why.So if some one has a clue please let me know.

 

possibly tps sensor, oil pressure sender

 

Injectors may be effed also. Go cheap and work your way up.

 

I finely figured it out, it turned out to be the ignition module. which is located under the distributor cap. I went to a lot of different sites and at least this site tryed to help. There is a lot of worthless sites just looking for money and this site is not one of them. I appreciate the suggestions and people who just help others without trying to take there money. thanks

 

Glad you fixed it.
