Hi everyone:
I've got a 99 with a 2.7L with about 100k miles on it. Bought it in non-running condition from original owner's family. Car is in real nice shape. Always serviced right on time according to the guy I bought it from (but no paperwork to back that up since all the records burned up in the California Camp Fire).
When I first got it, I tried spraying some carb cleaner into the intake hose and it backfired so I was thinking it had a fueling problem and/or had jumped time.
The guy I bought it from was the (young) great grandson of the original owner and he overfilled it with oil so I was thinking he was doing some spirited cornering with it down on oil a bit and he starved the pickup tube which pumped the tensioner full of air.
Since I didn't have any records of a recent timing chain and water pump servicing I just dove in to that. Well, when I got in there the timing in fact had NOT jumped but since the chain was at least half way stretched I went ahead and changed/upgraded the chain, sprockets, and pump.
Now I'm reassembling and I wanted to try and test fire it so I could figure out what the *real* problem is. I've put back together enough stuff such that it *should* run but I'm not even getting a backfire (but the coils aren't being pressed down by the cam covers cuz I just have them stuck in there w/o covers and they seem to pop-up a bit and not really clamp onto the top of the plug so I'm guessing the pressure of the hold-downs keep them in tight contact together).
I have a fuel pressure gauge on rail input and it maxes out at 46 PSI after flipping the key on a few times. It holds pressure pretty well leaking down to about 33 after an hour or so.
I was going to check to see if the fuel injectors were even firing so I pumped it up to its normal 46 then pulled the fuel pump relay and cranked it and it seems to drop about 1 lb for every second of cranking. Would that be about the normal amount?
Any other ideas of what I can check or how to proceed?
TIA,
-Kevin
