OK...........I'm out..........
Just so you know, the 2.5 TBI only needs 14-17psi, it's regulated to that, you can use regular hoses and clamps if you need to.
OK, well clearly it's not moving any fuel.
Has it occurred to anyone that you have a bad pump????
It maybe that the pump has gone to ground and therefore the relay stammers.
Time for a pump.......and go through ALL your grounds and cables and fused links...........ect.........
If it were me...........
I'd be looking at '94 XJ as a donor, you'll get the external slave that you'll most definitely want. Look to '97 up for a rear axle.
I have an NOS copper/brass that has been sitting in a box since 1991. I won't be using it since I'm going V8 and will need to get a custom rad built.
I paid $200 plus shipping, will need the same if you are interested. Just an offer..........
The plastic/aluminum ones from the parts stores are cheap, IIRC, $120. I've gone through 5 of those, lifetime warranty. Current one is a good one.
The last tooth is worn out.
Pull the bottom of the door card, stick your fingers in and lift on the glass as you roll it up.
Did that for a year, sucks.
Go to a 97up door.
Based on the sound on your vid................
It sounds like it's the same no matter where the camera panned the VC....is this correct?
If this is correct then you would have to conclude that all 6 pistons are slapping and I cannot believe that.
Clacking sounds like rockers to me, not piston slap.
'86 harness is different from the ' 91 harness.
Pull the driver's tail light out, there should be a wire that is screwed to the sheet metal, clean that ground.
I'd suggest reinstalling the original ECU.
And test your fusible links, all seven of those...........they belong in the trash but that's another matter.
