Did you check for voltage and ground at the fuel pump relay? Engine cranking do you have spark at the plugs?

In the diagram, fuel pump, load side, that line with arrowhead is hot all the time. Is it? Voltage for coil side of relay, left side, comes from the eec relay, which should energize with the key on. The bottom wire on left, is ground for the coil side of relay, controled by computer.

Have you checked for codes?

I was going to post a diagram, I forgot.

Some of the discount stores sell a digital multimeter, you really need one to do your own testing.

You don't need a code reader to test for codes. I'll try to post the procedure for checking codes in a bit. I don't have it right in front of me.

The fittings below, should be located under the hood, passeger side fender lining, close to starter relay. The test is key on engine off. You can use a testlite between terminals indicated, the lite flashes. The real fast codes, you ignore. The slower ones, you write down. Two digit codes, a 24 code, would be 2 quick flashes, a pause then 4 flashes.
