What is the enigne vacuum at when it is at an idle?
i am checking that tonight and will let you know. i also plan on doing a leakdown test to double check the valves.
i dont think so. im pretty sure i just plug my vacuum guage into the pcv port right?
I am sorry. I should have ben more clear.
Would you like a wiring diagram of your timing belt and timing marks?
Well, if the vehicle wont go over two miles an hour, then something is seriously wrong.
I would honestly start by checking engine vacuum and valve timing. Even if the marks were on, the timing belt may have jumped and are now off.
If its not a mechanical issue, then add some propane to the intake and see if the engine power comes back. Just be sure that the there are no air or vacuum leaks.
Well, the ticking could just be the upper engine of the engine. I would verify that the oil pressure is just fine. IF it is, then the lifters may need to be replaced. If oil pressure is low, then further investigating is going to be needed.
TO add propane, just open the air cleaner box as if you were changing the air filter and inject propane into the air snorkel that goes into the intake.
The oil pressure sender is just for the light or oil gauge (which ever one you have)
If the engine vacuum is low and the timing marks are dead one, I would believe it would be because of the lifters. Maybe they are out of adjustment somehow or over adjusted?
I don't believe that they are adjustable but maybe this is why they are making noise.
Engine vacuum should not affect oil pressure. But a mechanical problem with the engine could affect both..oil pressure and engine vacuum.
LEt me know what you find!
I hope this helps. You can always accept my answer now, and repost back again later on if you have any more questions. If you want to discuss it some more just hit "reply", it's free to do so otherwise don't forget to hit "accept" and leave positive feedback if you found my answer helpful.
You could spray just a small mist of starting fluid into the intake and see if the engine vacuum comes back up. Whatch the vacuum gauge as you do this.
But, I think we might have a bad computer. Check this out. Code 55 means that we have an internal failure in the computer. Here is the description
System Operation and Code Output These diagnostic trouble codes are output when a short circuit (No.54) or open circuit (No.55) occurs in the squib ignition drive circuit inside the SRS-ECU.
Malfunction of SRS-ECUTesting - Corrective Action
