SOURCE: 1993 Acura - intermittent fuel pump operation (no start)

HI...
The common cause of the problem that you related.
Is the FUEL PUMP RELAY " Called MAIN RELAY.
Is located : left side under the dash.
Is a BIG relay gray colour. with a connector of 7 or 8 wires.
I recomend replace the relay.

And letme know if you solve your problem.

I hope this information work on your problem.
Thank you for use fixya.

you need ot do a tune up, these problems are ussually associated with bad wires and coil packs...

i would say maf 2

SOURCE: my '94 Jetta turns over but will not start.

sounds to me like either your in need of a tune up or there is a chance your crank position sensor is going out or finally gone.

You might have leaking injector(s) or injector O-ring(s). It could be leaking inside the fuel rail feeding fuel constantly. The pressure could be OK because the computer compensates by working the fuel pump harder in order to keep pressure within specs. I have a similar problem in my 99 Outback, it rough idles at stops intermittently. I recreated the problem, I checked it in my back yard, turned it on, let it warm up. Then I put it in gear went forward stopping and going with the e-brake until it rough idled. I got out put some bricks in front of the tires and started checking around. I noticed when it rough idles the transmission makes a constant sound. I would describe it as a fast ticking, sounds electronic. I tried messing with the idle by adjusting the TPS. I noticed that when I set the TPS to where there was little or no signal coming from it the sound would stop and the idle would be normal. I haven't had time to check it again but I don't know what to think of it.
