Customer: replied 3 months ago.
ok no good followed step by step
Expert:  kalamykid replied 3 months ago.

Do you have a digital volt meter, a test light, and a fuel pressure tester?

Customer: replied 3 months ago.
no i dont have any of those,but what course of action do you suggest,what should i be looking for,pressure at the fuel rail,a shorted wire on the harness,injector pulse,i think i do have a volt meter,how do i test with that,if you have a bad icm will you still get spark from the coil packs
Expert:  kalamykid replied 3 months ago.

Sections of the icm can go out and you still have spark to some if not all of the spark plugs. What we really need to know first is what is the fuel pressure with the key in the run position. We also need to know if the injectors are getting a pulse signal from the pcm. From there we will know where to go next.

Customer: replied 3 months ago.
ok ill borrow the tools mentioned,so how do i perform the test,for,icm,fuel pressure, and pulse signals thanks
Expert:  kalamykid replied 3 months ago.

See what tools you can get in the morning and drop me a line here letting me know you have the tools and we can go over each step one at a time with the tools you can get. S lets meet back here in 10 hours?
