Default Car won't start again!

ok so 10 days ago the car had problem starting, found out it was the fuel injection relay cause the very last time the car ran was after i towed the car home and jump the injection relay and it ran, today i put in a new relay from Roger, the car starts right away BUT it died 5 seconds later, restart no joy, just cranks and cranks, i also tried jumping it again and this time no start even by jumping, i m really lost now, please help!

I had a problem in the past, use a noid light to check that all of the injectors are getting power. If not it could be a fried ecu, bad fuek inj harness, bad crank sensor. Also check for corrossion ecu connector.

Lol that remind me. I had my internal fuel pumo clogged so it would not send fuel. Someone made a post on how to check if both are working. I would start with a noid light. You can rent one cheap from autozone. It the fastest way to see if the injectors are getting power.

Fuel pump age...unknown, new fuel filter tho
Not sure about injector getting power or not....new plug and coil wires couple years ago
Fuel pump clogged maybe
Its 84 US
This time no start is a little different than 10 days ago, jumping either injection relay and fuel pump relay no success, no fuel pump sound this time, i am going to bypass the alarm tommor z4 and z6, found some old thread about intermittent no start so give that a try

Well, bypass the alarm, still no start......

Either it will sit til next year or i'll just sell it cheap
Thanks all
