Hi there. Thank you for posting your question!
I’m a retired master technician and tech instructor, so I’m pretty sure we can solve your issue together. However, before we start I need you to please consider the following facts:
- I do not know your skill level or what tools you have
- It may take a few back and forth replies to solve the issue
- There will probably be some tools and equipment needed for a proper diagnosis
First step should be to see if there are any trouble codes.
To retrieve codes, install jumper wire between ALDL diagnostic leads. See Fig. 1 attached. Turn ignition on. Count number of flashes from MIL to identify code. See Fig. 2 attached. For example, Code 12 will be flashed as follows: flash, pause, flash, flash.
If system is operating properly, Code 12 should be displayed with ignition on and engine off, indicating diagnostic system is capable of storing codes.
Code 12 will flash 3 times, followed by any stored trouble codes. Each code will be flashed 3 times starting with lowest code. Once all codes are displayed, cycle will repeat. After codes are retrieved, remove jumper wire from diagnostic leads to exit diagnostic mode.
After retrieving codes, second step should be to check fuel pressure (should be 35-40 psi).
Once we have that information, we can proceed with our diagnosis.
