Re: 98 ranger sohc won't run
I'm not near the truck or I'd look. Either way, let's just say it is because its the common engine. I'll change the thread to ohv. Do you have anything helpful?

no they don't rangers had the OHV until 2000. Glad to see you don't know what you own.

Low compression could be bad rings, cracked pistons, faulty headgasket,

Re: 98 ranger sohc won't run
Already checked all that, fresh heads, all good gaskets, rings arent bad, good fuel pressure, its firing. However when you do get it to run it only runs off of one cylinder, missfire on the others but they all have the same compression. I think it had 90 pounds, its been a few weeks since I'd messed with it. But if they all have low compression why would the one cylinder rum and no the others? The injectors are working, its in time, I think its computer

Re: 98 ranger sohc won't run
the PCM very rarely goes bad...and 90PSI of compression seems awfully low to me..should be well into the 100s
EDIT: normal compression is 130 or higher

Re: 98 ranger ohv won't run
it should have about 120 at the very least just to run but they all have the same so why would it miss on all but one cylinder? whats different about it? and there is no obvious reason for low compression. which makes me think that its not firing at the right time because of the computer

The only way to check the rings is by tearing down the bottom half of the engine. You said you did the heads and gaskets not the bottom end. Also you could have a bad cam shaft or the timing may be slipped.

Lol. How much more helpful could the guy be. He figured out what engine you have.
