Driving down the road and engine shuts off

[Jimmycxc]

I as out for a normal Sunday drive and all seemed normal. I was stopped at a light and as the light turned green, I started to take off. Continued on the gas until about 50 mph and then the engine just shut off on me. I pulled over, tried to start it and nothing. It cranks, but will not fire.

A similar thing happened the week before also. I was out for a normal drive and as I was turning, I put pushed the clutch in to downshift into second and the car's engine turned off on me. I quickly put it in neutral and turned the key and it started right up for me.

Its not the RPM relay as I have the upgraded one. The battery charge was low, but it initially started fine. I had the alternator replaced with Harvey's about 4 years ago. Could the alternator have gone bad? I have since charged the battery, but it still will not fire. Fuel is a little over a quarter tank.

Thanks

This is almost the same thing I ran into with my car. The fuel pump died. May want to check there.

Also check your connections at the inertia switch.

On mine, I've had this happen a couple of times. Once was the Fuel Pump fuse (#7, IIRC) and once was the Fuel Pump power connector. I'm using Hervey's "all-in-one" style pump, and I've since zip-tied the connector together.

I have had this happen as well and it turned out to be the #7 fuse not being held tight enough. To get home I had to leave the fuse area open and manually press the fuse in to keep the pump running. Once home I backed out the female spade connectors and tightened them up. Problem solved.

In my case it was the 12V connection on top of the coil had worked loose.

Thank you. I went to check those things out and then tried to start her. Didn't hear the humming of the fuel pump and fuses are good. Looking like a new fuel pump is in order.

Don't buy a new fuel pump yet! Measure the voltage at the harness. The fuel pump seems to have a voltage threshold around 11 volts. If you see lower than that its probably a ground issue.

Which color wires do I check?

In my experience, the wiring on the white ballast resistors is the really bit offender on this one, but all the other things mentioned can happen.

Jump the RPM relay too, and/or replace it. New things can fail.
