    Another simtom of the car is that when I changed the cap and plugs the cars tach was bouncing at around 3 grand.. at highway speeds... im looking for used parts now that you recommended before I buy new and it doesn't solve it... im a student at UTI and one of my instructors told me it could be the feul cutoff sololoid maybe even the distributor itself further help is greatly appricated!

    Thanks for the update. Glad to see you got your car running. Are your teachers automotive instructors?

    Lol yeah I go to universal technical institute and they all were thinking it was some kinds of fuel issue but I knew I checked the pressur and it was good and then with your help about the coil and icm I went for the coil first cause my sister in law works for a body shot and had acces to a used one so when that didn't work I checked all data and it said if the ICM is wrking the tach should operate normal and so I knew it had to be the icm and it worked!

    Yes, the BLU wire from the ICM goes directly to the tach. Erratic rpm is often a dead giveaway that the ICM is toast.

    90%+ of "crank but won't start situations" and poor performance problems are electrical-related, not fuel. I have never seen a bad electrical fuel pump on a modern-day car. Many get replaced, however. Instead, the "fuel problem" usually involves a fuse, relay, ECM, or ignition switch. It's important to have a detailed understanding of how the whole electrical system works.
