Starting issue....

Postby smonop » Wed Jun 27, 2018 7:55 am

In a previous thread I had issues with the distributor and electrical system which was solved by the well known Porsche guys at Provost motors, near me in NJ ( as you boys had recommended he added a resistor etc. solving the problem). Yesterday went to start it turns over but won’t start. Upon further inspection I noticed that I don’t hear the sound of the fuel pump engaging. I’ve checked all the connections everything seems to be in order. I replaced all of the fuses underneath the dash for poops and giggles. Thoughts? Bad fuel pump? Something I’m not considering?

Bad ground or no power at the pump. If they check OK, the pump is probably bad.

Danny's right. I just went through this. See if you can run a "hot" wire directly from the battery or a known live 12v source to the pump. This would eliminate any fuse/switch issues. Same on the ground side. Run a wire from the pump to a known ground. If it still doesn't run, then it is the pump. But my experience has been that electric pumps are usually very reliable.

So I ordered a new fuel pump from Greg at vintage since mine is now 12 years old. In the interim, I removed the existing pump and tested the live wire coming through the dash, my test probe lit up at least telling me I have power to the wire and which would seem to tell me the pump is the issue? As an aside is there an adequate replacement pump I could’ve gotten at my local AutoZone? My current set up runs an E8016S, which from Googling seems everyone and their grandmother makes and sells for anywhere from 30 to 50 bucks

I had that pump on my old Spyder. Flawless service for 11 years. I got it at Autozone but now they have a little square one(not a Facet though). But like you said, available almost anywhere.

On the new car I'm running a Carter rotary pump which is currently unavailable on Amazon: https://www.amazon.com/Carter-P60504-Li ... B000BZX92K

But is available here:

Thanks Danny. I stopped by AutoZone they carry one that is cylindrical under the same model number, it’s just smaller in diameter as is the filter.

Advanced Autoparts also sells a version under their name brand, Carquest. From what I surmise in looking at the part, they’re all the same thing branded under the company that chooses to sell it. Greg shipped me the one I ordered today, hopefully it solves the problem!

It should. Do you have good, clean fuel at the filter IN?

I don't have a shutoff there below the tank. I take a pair of needle nose vice-grips and slip 3/8" copper tubing over the jaws to make a ghetto-type hose clamp, shutting off flow. This works and doesn't crush the fuel hose. Good luck.

Well, I received and installed the new fuel pump and I got nuthin... sigh... before installing I tested the live wire and the probe lit up, so I know there’s power. I also double checked to make sure the ground wire was secured to the frame... but when I finished and turned the key I didn’t hear bubkus (no rattle, no humming) out of the new pump and she still doesn’t start... ugh... now what?

If the pump is good and it gets both power and ground it will work.

Test the terminals - I have an elcheapo autozone quick power tester that is essentially a lightbulb with a probe and a ground. It's non directional, so you can touch 1 end to the ground wire and one to the power wire. If it lights up the then you have both power and ground.

Test the pump outside of the car by connecting the power and a ground to make sure it works. Just a quick connection will let you know the pump spins. Then install it. You want it mounted firmly, but do not over tighten the band around the pump. I have heard that over tightening them can put pressure on the motor and cause it to burn up.

Good luck,

Test the wire again, it's possible you blew the fuse.

Problem solved! I started from the beginning and followed your collective advice verbatim, step by step. It was the dang ground. When I relocated the fuel pump (one hole vertically on the frame for easier access) I didn’t take into account that the new location was painted (the original location had been sanded to bare metal).

I disconnected the fuel pump power and ground wires from the car. I connected the test probe to a known ground (bolt on frame) and with the key in the on position I tested the live/red power wire - the probe light lit up. I repeated this sequence using the painted part of the frame I was using for the ground, not surprisingly the live wire did not light up. To remedy, I connected the ground to the clamp holding the fuel pump to the frame. Music to my ears to hear that fuel pump rattle and hum when I turned the key on. Car started up right away.

You guys are the best. Thank you very much.
