i just bought a 1984 RX-7 GSL-SE YESTERDAY! and last night i got stuck on the freeway, it seem's like the fuel pump gave out, replaced it, still not running, sound's like the pump is gettin little to no power what so ever, any tip's or possable culprit's to for my problem? any help would be much appriated

Without condescending, I'd check all the basics first. Check fuses and sparkplugs and replace the fuel and air filters (and oil, but that wouldn't keep it from running). The fuel filter could be part of the problem., though I'd make sure that you are getting spark for sure before getting too crazy about the fuel system...it's easier to check. Also, it could be flooded if you were trying to start it for a long time without success. Take the wire off the front coil (nearest the headlight) and start it that way. It'll die pretty quick, but then plug it back in and it should start if that's the issue. Good luck!

I meant to stress more on the fuses too...if your fuel pump went, it may have blown the fuse if it froze up.

make sure the trailing ignitor is firing, if its not the fuel pump relay is wired through it, if the ignitor goes out, the pump stops....

also check the fuel pump relay, its under the ECU cover on the passender floorboard, sometimes the relay goes out..

did the car just stop running? or did it get proressively worse?

me bein newish to diganoseing car problem's, i didnt catch it, but it's been sputtering every now and then like it would if you ran out of gas, and then just picked back up, last night it stopped completely tho and i got stuck on the freeway, i've checked all the fuse's, so i guess the relay is the next to go

was thinkin if the relay is out, since i cant find anyone with one (called practicly 50 place's, not includeing junkyards) could i replace it with a toggle switch, my uncle mentioned something about it in a passing comment about race car's and it stuck in my head, any problem's that could come from this or think it might be worth a shot?

i was told by someone that it's more then likely a sensor somewhere, he had me jump the relay or something, then open up a trap door inside the air filter box, and each time the pump turned on, so he said it's a sensor playin up somewhere, anyone know where i might find the one that could be doin it? he was very vauge when he stated all this, and now i cant get em again
