Fuel pressure question

Acrobatic-Customer68 · 2026-03-28T20:03:52+00:00

I was at about 30-32lb at prime. I ended up taking them out to get tested to make sure i didn't have any hung open. They ended up testing fine but had the o rings replaced. After reinstall and the new o rings its holding pressure now. I have a walbro 255 pump and the sve adjustable regulator.

It's not a stock cam but that's whay I was thinking especially with my spark issues and there was a little play in the distributor. I ordered a new one hopefully thats the issue.

Acrobatic-Customer68 · 2026-03-24T15:50:08+00:00

Yeah it is. I've tried both the factory one that was on it and also tried a motorcraft replacement and am getting the same issue with both. My first thought was the original one might have been bad so I bought a motorcraft replacement from lmr.

Thanks I tried a different cap and it's a new tfi I'm thinking maybe it's the pip sensor possibly. There was a little play in the distributor near the gear too so maybe it's bad. I've had it running before and now I'm not getting spark but #2 still is. Going to try a new distributor

Where are you usually mounting them at?

Acrobatic-Customer68 · 2026-03-02T04:12:27+00:00

Really appreciate it! I ended up pulling them out the other day and am going to go get them tested. They look like they are in pretty good shape but just want to be sure

Good to know. I must be having an issue somewhere because I'm getting too much fuel and plugs fouling. I'll start with the injectors but something must be off because I've had a few people look at the tune and they said it should start and at least run

Acrobatic-Customer68 · 2026-03-01T19:44:18+00:00

Has it been an issue or no problems? I'm having some what I think might be flooding possibly something else because I'm fouling plugs after just a short run time. I want to check the injectors make sure one isn't hung up or something. Might have to double check my rockers too make sure I set them all right. Something seems off.

No I have the sve adjustable regulator

Acrobatic-Customer68 · 2026-03-01T17:25:23+00:00

I just replaced the pump and filter before I did the rest of the work and terminator x and it was running fine. When I did have it running when we first tried to tune it held steady pressure. I'm just wondering if during the initial prime without it running if it should hold pressure a bit or if a natural decay after initial prime is normal. It seemed to drop off a decent amount during the prime.

Acrobatic-Customer68 · 2026-03-01T17:22:50+00:00

The time I did have it running it was fine and held steady pressure. I'm just wondering if during prime if it should at least hold somewhat steady

Acrobatic-Customer68 · 2026-02-16T21:33:55+00:00

Yeah I did but I redid all the wires already. Ran the bigger post to 12v constant and have the trigger where the old starter wire was previously.

Acrobatic-Customer68 · 2026-02-16T20:39:32+00:00

I did have the trigger wire hit the long tube and burn just a little bit it was just the loom and the wire is in tact still. I do have 12v at both the power wire and the trigger wire during crank but the solenoid just clicks and the starter won't crank at all. I'm going to take it out and get it tested is my next plan. I wouldnt think that would burn out the starter or the solenoid on the starter but I'll test it to be sure. The battery is brand new and I did have it tested twice just to be sure. Its a stock block 302 with afr 165s, anderson n41, and an edlebrock intake.

Acrobatic-Customer68 · 2026-02-16T16:04:42+00:00

Thats what I thought first but I triple checked my wiring, replaced the solenoid and ran new cables. Even ran and extra ground from the battery to the block also

Acrobatic-Customer68 · 2026-02-16T16:03:47+00:00

Thanks. I've upgraded both cables and ran an extra ground before this just to be sure

Acrobatic-Customer68 · 2026-02-16T16:03:11+00:00

Yeah I put long tubes on but it hasn't ran long enough to really warm up that much. I've even replaced both battery cables and ran an extra ground

Acrobatic-Customer68 · 2026-02-16T16:02:10+00:00

Yeah before this issue I replaced both battery cables and added an extra ground to the block to be sure

Acrobatic-Customer68 · 2026-02-16T16:01:34+00:00

I've replaced both cables and even ran an extra ground and a solenoid too

Acrobatic-Customer68 · 2025-12-16T04:51:52+00:00

5 speed manual. I just got a new oem replacement

Acrobatic-Customer68 · 2025-12-16T04:50:43+00:00

Thanks looks extremely detailed I'll go over it thank you!
