So I drove home in my Del Sol and out of the no where it doesn't start anymore. It cranks but doesn't start. So I decided to start checking it out to see what it could be. I checked if there was any spark and nothing so I thought I needed a new distributor and no luck.. It didn't turn on. Then I saw that it wasn't pumping any fuel into the engine. I thought it might of being the main relay wich I also replaced and no luck either. I went ahead and checked to see if it threw any codes or anything like dat and well the check engine just stays on when key is forward and doesn't blink or anything like that so its not giving me any codes. Since it didn't blink I thought it might of be a code 0 so I went ahead and checked the fuses and the ground from that is by the thermostat and still no luck!! I don't know what else to do or check other than to replace the ECU wich I would hate to spend money on it and for it not to be.. Wat else can I do!!?? I would really appreciate any help!!! Thanks!!!

Voltage test fuses 31 and 24.

Clean and tighten the G101 ground on the thermostat housing.

If all else fails, swap in a known good ECU.

R fuses 24 and 31 the ones on the fuse box from the engine bay? If so I got all those check and r good.. Also cleaned and checked the G101 Ground on the thermostat housing and nothing.. Just running out of ideas...

Fuse 24 is the 15A fuse is the dash fuse box.

Fuse 31 is the 15A fuse in the hood fuse box.

It's best to voltage test both. Click the fuses link in my signature.

Is you battery good?

2.does fuel pump prime? You should hear a hum for about 3 secs from behind the seats
Y-3
N-replace

3.follow spark and fuel to motor: do injectors get fuel and dizzy get voltage?

Think linear my man. Spark- Fuel-Air. follow one all the way through.Cars are simple. Diagnostics aren't. You have to apply K.I.S.S.

I have a 93 sol si. Same issue. Mine ended up being my dizzy and shitty connects in the harness. I'm not a mechanic by any means, but I've had my sol for 11 years (1st car) AND I stayed a a holiday Inn express last night :-)

No fuel and no spark... Changed distributor and ecu and no luck... Don't want to spend on a fuel pump if dats not going to b the problem...

Stop replacing parts at random and do some troubleshooting tests.

A bad fuel pump would not prevent spark.

Dats wat I mean reason y I'm sure it's not the fuel pump... Any more ideas?
