Engine/Transmission (1994 - 1998) No Start

[jeepullr]

In my attempt to recover from my melt down. I've replaced all the injectors with 215's from PDR. Followed their instrucions for install. Put the truck all back together. Did a line bleed (leave fuel line to injector fastener loose and crank till they show fuel then tighten down). Got all injectors showing fuel, tightend them all down. Restarted, ran fine, went to bleed again while running (as per PDR instructions). Loosened 1, idle dropped back, re-tightened ran fine. Loosened 2, idle dropped back, re-tightened ran fine. 3 and 4 were the same. Got to 5, loosened it and it stalled. Cracked the fitting open again and gave it a crank. Plenty of fuel squirting (at least it's the same as 1-4), tightened everything down. Now It won't start at all, just crank... not even a hiccup to make me think it might start. All wires seem to be where they should be, I've installed 2 new batteries (cranking killed a cell on one of the old ones), Fuel shut down sel. moves up when cranked...



What else should I check??????

push on the primer on your lift pump about 20 times and listen if the overflow valve "sings". Then try starting it.

Just finished removing all soft lines and connections that were put in (and since bypassed) for the grease and the secondary fuel filter (put on by PO). Just one 6 inch pc of new rubber and 2 new clamps. Pumped up the lifter pump 14 times before I got the injector pump squeel. Went another 5. Cranked for 20 seconds. NOTHING. Let it sit 3 minutes. Hit lifter pump 12 times (squeeled after 8). Cranked for 20 seconds... NOTHING again... Walked into garage, opened refrigerator, pulled out Dead Guy poped top, sat down on 5 gal bucket, quaifed beer, stared at truck. Gave up for night... Will open all connections tomorrow, re seal, try again.

have you pulled the plug on the fuel heater to see if the connector is melted and leaking fuel/letting air into the system? You could try removing the heater also. Just take it off and the "stud" will unscrew will an allen wrench and then the strainer bowl will bolt right back up to it.

Went out this AM and opened and retighted all fuel related lines... From the soft line at the tank, forward to the pumps, pumps to injectors, injectors to returns, to soft return line at the tank. All rubber is new, all new clamps. Several pumps of the primer button. Mash the throttle, Crank. Got a pretty good stumble while cranking. Let it sit for 5 minutes, moved all the tools off the radiator. Cranked again. We have life! Ran for a few seconds. Crank again and it roared to life. Let it idle for a few minutes, cleaned up the tools and put them on the work table. Moved some of the tarp lines and the EZ-up (yes, it's raining). Pulled out and took it for a 6 mile "around the block". It feels down on power some, and the turbo doesn't hit as hard once it's spooled up (no kick in the pants). Got back in the driveway, popped the hood. Most everything sounds good, no clanking or banging... there is is very faint "huff, huff, huff" from the back of the motor. There is some fuel leaking from the #5 and #6 injectors. So I'm guessing I'm still getting some air (hence the 'huff' noise). Letting it cool some, will clean it up, re tighten #5 and #6 and see what happens from there.

Still a problem... Looking for a magic bullet at this point. Spent most of today futzing with it... Still no start.



Fuel shut off selenoid pulls up at every attempt.

I've got good squirts from the fuel lines at the injectors.

5-6 pumps of the lifter pump primer and I'll get the bypass squeel.

All rocker arms look good and move as they should.

All valves appear to move as they should.

Pump seems to be in time (by watching #1 valves and fuel squirt at injector).

I've tried blocking off the return line and cranking, no change.

I've double clamped both rubber (new hose) lines.

I've put on a new fuel filter (and primed it)

I get pressure at the fuel filter water drain.

I get pressure when I crack the return line (at the injector)

I've checked, double checked the hard fuel lines, taken them off, put them back on, checked and double checked them again...



I'm running out of ideas... and patience



Anybody have any more ideas?
