Can't figure out Cranking Issue!!!!!!!

[Charlieb60]

This is driving me crazy...here's what's new on my truck:

Brand new Battery
Brand new spark plugs
Newer Ignition Coil
Newly installed fuel regulator
Radiator's been newly flushed


OK...so what's the prob?

My 89 3VZE Auto will not turn over...just crank, crank, crank, a few rumbles, then just more cranking.

It just won't get to the point where it will turn over and stay on. I had to replace the battery, because the cranking was causing the battery to die and then nothing would happen.

With new battery that doesn't happen, but I don't know where to go next. I've had two mechanics say the start is not the issue, so.......


Really annoying...

On a related note:

Truck is SLOOOOOOOOOW to accelerate, especially climbing hills. I mean like crazy slow when in 2wd. In 4WD, especially 4Lo, it's a monster and will climb anything.

The other day I stalled out at a stop light and had to start her again. That's never happened before, so not sure if that's related.

I had mechanic run a compression test, and he said it's (110 on each cylinder).

I just thought I would give as much info as I possibly could so someone might be able to lead me in a direction.

Thanks,

CB

Hi 110 lbs is getting close to low compression. My understanding is that it takes minimum, 100 lbs for a gas engine to run. That said, I have a 1939 ford tractor that starts and runs in cold weather below zero and it has 60 lbs. Once its warmed up it will not start. If the ambient temp is above zero it might start but it displays the same symptoms you describe. The toyota v6 has around 160 lbs plus when new, I think.

Hmmmm...i thought it was a little low.

My fear is that I've got snow coming this week and no4wd vehicle...always seems to give me probs at the worst times.

have you tried doing a leak down test and see if you have bad rings or a leaking valve seat? doing this test will help pin point the problem cylinders
