ok jus 45 mins ago, i was at a gas station. before that my del sol was runnin perfect. im done pumpin gas and go to start the car. its doesnt start. so i know it isnt batt., starter, or alternator cuz i jus tested all that 2 days ago. im thinkin its the fuel pump or somethin to do with the fuel.i dont hear the pump come on when i put the key to II,and its suppost to right?? i even tryed to pop the clutch while a buddy pushed still no luck.. can anyone give any advice to what it could be or had the same situation. thanx in advance

If you turn the ignition switch on but don't start the motor and you cannot hear the fuel pump priming...you aren't getting fuel.

That could mean the fuel pump is bad, the relay is bad, or the wiring is bad. But most likely either your fuel pump died or one of the relays has gone bad...start with checking your relays.

My Si has done the same thing. Any chance this happened after a long drive, or possibly a hot day?
Mine has always started up after I let it sit (key off) for maybe 30 seconds and tried again though. The pump would turn on though, and I recently replaced the distributor, so I don't know how what I just said is relevant.

Rather than go on forever about this, narrow down the problem first. Start easy with fuses, relays, etc. Pumps usually die slow, they whine for a while, then die. Generally in rush hour traffic when your already late for work. You should be able to hear the relay click when the CEL shuts off, take the back seat out and you should be able to hear the pump go for that couple of seconds. If that checks out, get a pressure tester and don't blast yourself with fuel. Or turn it over for a few seconds with one of the plugs out and smell for fuel.

btw, Alternator has absolutely nothing to do with starting the vehicle.

Just a suggestion, check out a junkyard for the label on the fuse box "door." It's nice to have.

--to check if u really have fuel goin to the rail is to take that return line after the fpr and have someone turn the key to ON and see if theres fuel coming out of there. then if theres not then check fuses. then if they are good then check if u can hear the MAIN RELAY is clicking, if it does then the relay is good

--do u have spark? pull one of the wires and put a screwdriver and c if u have spark coming out

sounds like main relay. They can create a magnetic field on hot days and that fries the relay. so check that. I believe they're like 60 bucks at the honda dealership

ok well i jus got back home and i figured id try to start the car. i put the key in and it fires right up. fuel pump primes and everything. my question is y did it do that??

yoru main relay is made up of metal components.

on hot days and with hot current running through it those parts will expand slighlty. this expantion will not allow full conttc of the main relay.

on cold days metal contracts. or after the vehicle sits fo an hour or so. this allows a better contact patch on this main relay.

where exactly is my main relay. behind the glove box or by the steering column. ive rad but none seem to clarify

to the left under the steering column, sorta around the fusebox. Should look like a little brown box, or maybe black or grey.

I'm almost sure that's what your problem is.

im pretty sure its it too. im gonna resolder it until mine comes in from honda
