1990 Ford F150 with 170,000 miles 5.0 engine and 5sp trans. Is there a fuse or relay to control the ignition. The truck cranks but doesn't start. I have been through the troubleshooting and have determined that the computer is bad. The problem is it never checked the EEC relay. Could this be the real problem and how do I check it. I am on a very tight budget and I hate to spend any more money on something that may or may not be the problem. Any help would be greatly appreciated.

Are you haveing a no spark condition? No gas?
Usually if you have a no spark condition, it's the tfi module on the side of the distributor.I will send the tests in your email.
