On my way home on the freeway last night, my 74 2.0L just died travelling along at 70 MPH. Had her towed home.
Looking at it today, it appears there is no spark. If I turn the key, I can hear the fuel pump so seems like I got power there. I have a newer Bosch coil from PP that I put in a few months ago (it's one of those silver looking ones but a Bosch unit). I replaced the coil back with the old one and still no start. Car cranks, but no fire. The car has Pertronix in it. I suspect this is what died. Does that sound right to the folks here? |

Sent you a PM, but before you go replacing the fuel pump you are sure the fuel filter isn't clogged?

Sent you a PM, but before you go replacing the fuel pump you are sure the fuel filter isn't clogged? Thanks for the PM. I'm pretty sure it is not the filter only because I don't hear the pump running when turning on the ignition. Sometimes it works (pump runs) and sometimes it doesn't). I'm starting with the relay board (heck its 40 years old as it is) because I am also having an intermittent issue where my AAR doesn't work. It's not a stuck AAR issue...it's a power issue. After that, I'm going to triple check the wiring to the pump given that it was "hacked in" to run off of power from up front vs. running power from the rear. I'll be honest, I'm looking at taking any of the fuel lines out from up front where the pump is dead last because I have 3/4 tank of gas. I guess my neighbors are going to get some free gas in their gas cans for their lawn mowers. At this point, could still be anything such as bad grounds, other rotted cabling, etc, etc.... I know, I know....it will be the pump needs replaced in the end. |
