Just a thought, did you fiddle with the spark plug wires?

STeeL25T · #**242** 04-25-2013, 07:50 PM

No. Fiddle?

From that video, there is something definitely very wrong. What kind of motor mounts are sitting under that motor? And what condition?

I also found removing the injectors from the rails to be a major PITA. I wish I knew some trick to getting them out, but I don't...

Sounds like it's running out of gas. Can you get a fuel pressure tester and see what pressure you're getting on the line leaving the fuel filter? Also, did you check the fpr before you reinstalled it and did you hook it up to the vacuum port in the intake?

I do not have a fuel pressure gauge, never tested it before. I'd have to borrow something to test it.

It's sitting on stock motor mounts. I can't tell you anything about the condition.. They aren't new but they don't appear to be leaking. I have a pair of brand new Group N mounts in the back seat, but they haven't been modified to work yet. I intened to drive the car to a shop to have it done when all this started happening last year.

I tried unplugging just the first two injectors closest to the front on the left ride. The first one didn't seem to do much, the second one seemed to make it worse, so I thought I'd just try my luck with replacing that first injector. I have 5 of them still in the fuel rail off my spare engine. Well, 4 now.. I can't get the ****ers out of there without destroying them. Looked up a quick guide on removing them and the video says they should simply pull right out... Not happening. I couldn't pull out out with channel locks...

That really sounds like no spark at one/or more plugs or over rich/leaking fuel injector.
Someone mentioned checking the oil is the level higher then normal, does it smell like fuel?

STeeL25T · #**247** 04-25-2013, 09:29 PM

As best I can tell I'm actually losing oil. It was low when we checked it over the weekend. Lower than full, anyway.

Stupid question, but are the fuel pressure and return lines on the correct way?

Soak them in WD40 overnight. Rotate them 1st, left to right, etc., then carefully pry under the connector boss of the injector. Too easy to break with channel locks...

I think so at least. It worked well enough to drive around the block a hand full of times, to the gas station and back, to the mall for dinner and back home, etc. before this all started. The motor was out of the car for around a couple years though so it's always possible I don't remember where something went. I can take a picture of anything you'd like to check.

dragoontwo · #**251** 04-26-2013, 08:07 AM

It's a quick and easy enough thing to check out so sure.

TomsSVX · #**252** 04-26-2013, 11:51 AM

fuel lines look to be hooked to their correct places on the engine. The engines sounds seriously out of time... whether it be spark or just a mechanical issue. Might want to pop the timing covers off of the sides and just check that the cams line up with the timing marks

Tom

SVXRide · #**253** 04-26-2013, 01:37 PM

^^^^ what Tom said. Also, are you running a Hydra or the stock ECU? It's hard to tell from the prior posts in this thread. The MAF should be removed if you're running the Hydra. Are you sure the harness to the ECU or Hydra is fully seated?

Bill

STeeL25T · #**254** 04-26-2013, 01:42 PM

Stock ECU right now. I've switched to the Hydra once to see if that would change anything but no dice.

Thanks for the clarification. I'd suggest you go back through all of the harness connectors that you had to disconnect/reconnect when you pulled the engine. This would be an easy check prior to pulling the timing belt covers as Tom J. has recommended (and I agree with!!).

Good luck tracking the gremlins down.

Cheers,
Bill
