[hugo]

help!!!! so my 93 del sol, died on the hwy. it cranks but no start, diagnosed to a no spark, no fuel pump prime. replaced a new distributor, a new main relay, a new fuel pump. Every so often it will start but after a couple of rounds around the block it will die and wont come back on again.
and so it stands at the same problem, with no spark, no power to duel pump. checked and double check fuses, grounds , starter relay. please anyone can light up my day, week.

If you have replaced the main relay, I would look at your ignition switch. Jiggle the key around and see if it will start or power your fuel pump.

yes, i have replaced the main relay and did wiggle the key and still do not get power to the pump, please note that this is somewhat intermittent since at times i am able to turn it over, but they it dies again and wont start again.

I would troubleshoot the ignition switch with a meter and make sure you have power going where it is supposed to in start and run positions. Because what you are indicating is essentially the ECU and fuel pump are not getting power. Short of the main relay going out, the ignition switch would be next. Hopefully you have an electrical manual for the car.

i can try that, however about a year ago i replaced the ignition switch as i was having a starting problem and i had rebuilt the starter. after replacing the ignition switch still no luck at which i replaced the starter and that solved the problem then. now, this is a whole new issue, crank, no power to the fuel pump and no spark.

Was the replacement ignition switch OEM or aftermarket?
