HONDA PASSPORT FUEL PUMP PROBLEM

1994 Honda Passport

Electrical problem
1994 Honda Passport 6 cyl Four Wheel Drive Manual

I've been having a continuing problem with this car, sometimes it will start and run just fine and sometimes it will not start at all. Fuel pump relay had a jumper wire ran from the fuse panel, came loose once, found that and then car ran great for a few weeks, now it's just hit or miss. It will start and run just fine sometimes and other times it won't fire at all, try it again in a few hours and it starts again. I've had the car in a shop, well that's what they call themselves anyway, what a rip off. They checked out the relay, said not the problem put on plugs, wires, fuel filter, fuel pump and thermostat $997.50

Any idea what this might be?

I dont know about you, but if I see a relay powered by a wire run in from a different location than it's supposed to be powered from, I remove the relay center and check for burned or shorted wires! I dont take a not a problem from a lame ass! Pull that relay box and trace a few wires! Do you know how to check for grounds and power? Have a fluke? Check for power at the fuel pump.

I had the car in the shop, he rewired the relay and put in a new fuel pump, what were you saying about the lame exhaust? It is lame!

You did not say they rewired the relay only that they said it was fine, Lame exhaust? Nope, Lame rear end (a_s_s) is what I said, tho it was probably cencored...Have the ignition switch checked out by a competent mechanic, if you dont trust the last shop! We need to figure out what's missing when it acts up...spark? fuel? and since it runs sometimes, the compression is OK, you need all three. So test when the no start condition exists. Here's a few links to our testing vids, watch these and report back with the missing ingredient!

Done like you said, first checked and made sure I was getting fire, has good fire, second, took relay center off and opened up, apparantly a security system or fuel cut-off was installed at one time hince the need for jumper wire. The splice done with butt connectors by the shop wasn't right, the wire wasn't secured by the crimping of the connector and was loose causing the " hit or miss" starting. I put the jumper wire back in place for now, first day off from work I'll go back in it and try a more secure repair under the relay center doing away with the jumper or might even go ahead and run a cut-off switch again. Anyway it's running again for now.
