hello i got this 79 supra a week ago not running . the guy i got it from had the head redone 2 years ago drove around the block and parked it for 2 weeks and when he want to start it again it wouldn't start.

well after alot of work i got it running but it has a problem, it wont rev past 2200 rpm, almost like it hits a rev limiter. and it runs a little ruff . i think its a timing issue . but any help would be great.

Image

i got some pictures of every thing,

this is of the cam and the pointer is lined up with the dowel like it should to be.

Image
Image

rotor pointing at #1 exactly

Image

i have the distributor almost to the stop to get to 12*

Image

here is the timing mark, its a little off, is that a acceptable amount?

Image

here is a poor video , you can hear it backfire once,its never done that before.

I am thinking that your crank and your distributor are off a tad. I would look at resetting the timing between the crank and the cam and also the distributor all at the same time. Not a hard fix, but a bit time consuming. I have been fighting this sort of thing with my wife's camry. I redid all the front seals and replaced the timing belt. Took me two days to get the crank and the cams lined back up.

i have played with it all day and it just made it worse. it must be a electrical or fuel issue become as soon as i switched to my spare igniter it went from 2200 rpm max to 3200 rpm max.

Either a bad FPR or maybe some junk in the tank/lines restricting fuel flow?

thats one thing i haven't done is check fuel pressure, i don't have a gauge. i will switch out the fpr with a spare and see if that make a difference. thanks.
