truck wont start please help
1986 toyota pickup 4x4 sr5, 5spd, 22-re unknown mileage.
The truck wont start. I have tried many things and at one point it was starting and running for about 5 secs then dieing, then i tried this fuel pump check thing ( http://www.4crawler.com/4x4/CheapTri...shtml#FuelPump scroll down to the fuel pump tricks) and i think i screwed it up worse ( now that i looked at the site again i think i may have jumped the wrong connector and fried something, but i dont know what) because now it wont start at all, still turns over but wont start, and the fuel pump wont turn on. I know the pump is still good though because i hooked a wire to it from the battery so i could bypass everything and see if it was still good, and it is. I tried replacing the resistors in the fuse block and the resistor in the engine bay( passenger side one) and i replaced the in cab open relay above the ECU, all to no avail.... the check engine light still will not turn on when i turn the key to the on and start positions like it should, and the fuel pump is not turning on. Ive tried everything that i can think of.... please help me .
Thanks,
Andy

You blew a fuse! I doubt it's your fuel pump!

Replace your EFI relay. If you hooked up in reverse-polarity, you have fried it. It sits in the fuse block on the passenger-side of the engine compartment.

Not sure of the colour on a 1st gen, but it is a larger 'fuse' type of box. If you pop the top of it, you will see a diode across two contacts. This is the relay that sends the signal to the computer that sends the signal to the fuel pump. No relay = no fuel pump = no start.
PS: I learned this when I hooked my battery up in reverse polarity. Fried the 80 amp and the EFI relay. Replaced them, hit the re-sets on a couple of relays, and I was back in business.

Sorry about the bumps, I'm out of town and connecting via the hotel wifi...waaaayyy better than dial up at home....
There are several relays that I had to re-set. One of them is under the dash, just over the pedal bracket. Looks like a little silver pot, with a re-set button. THere is another one in the right side kick panel, not certain about these locations for the 4 cyl.
4X4Lamm put me on to them about two years ago. If he doesn't chime in here, just PM him. Good luck and let us know how it goes.

This might sound like a retarded suggestion, but make sure you check all the fuses with a meter.
Sometimes they look perfectly fine but they're blown. I had one like that one time and I wasted like 2 hours until I found a blown fuse with the meter that looked good.
