Sr wont start

[E10]

Engine turns over, I have fuel, fuel injectors work. I did the timing from a guide on another website. I have spark in 3 cylinders the 4th one doesn't get any spark. Did the wiring myself.

My thoughts are it could be a few things, advice or opinions would be greatly appreciated

1) Bad Igniter Chip q45 (Bought off ebay a week ago, is there anyway to check?)

2) Bad wiring

3) Bad ECU

4) CAS (is there a certain way you have to do this? I just lined up the markings on it and put it back in. I'm not understanding the whole 180 degree and 1 degree)

5) Park/Neutral switch just a thought, Was a A/t to manual swap but if it was a problem the engine wouldn't even turn over right?

6) Compression. All 4 cylinders put out 90. I don't think that it would still not fire though, Ive heard people with 50 to 60 still turning on.

Really lost as to why it wont start, anyones opinion are greatly welcomed.

Thanks,

1 or more of the choices you put could be the cause. I think you need to see about investing in a new head gasket and checking your rings. You might have seen someone running with compression that low but its not a healthy motor. You want all 4 cylinders to be at least in the 120 on up. To go on what you have though, i would see about checking numbers 1,2,3,4,6. 5 shouldnt be a culprit.

90 compression is VERY low. May not be enough to turn the engine over. I'd start with head gasket and rings too. Good compression should be around 145psi and up.

I will check into replacing Head Gasket, but didn't think it was to old because you can see the tabs on it and it looks pretty new. It looks like the rebuilt the engine. I think it might be the rings.

I think its very low as well, but still heard people being able to start there engine with lower compression thats why not convinced its that.

Its not the CAS or timing checked that again today.

Anyone know how to check igniter, or Ecu? I don't see anything on the inside that looks burnt up.

The igniter i try to follow the wires but after it goes through the igniter from Coil pack plugs i lose it and cant trace continuity.

I'm really lost now. Going to buy a pre-made wire harness for the swap if anyone knows a good site other than http://www.wiringspecialties.com.

Thanks again,
Mike

Yea that comp is unacceptable, check yours rings is a definate. Wiring specialities is what I'm about to get, their harnesses look great, and have only heard good things about them. The ecu or ignitor idk much on. Maybe if one of the moderators in here could chime in, they can get you rolling soon.

Did you do the compression check with the throttle open? How did you do the wiring for the Q ignitor? The CAS need to have the dots lined up and the engine at TDC on a compression stroke. Are you getting any sputtering or anything when you are trying to start the engine?

Compression check was done, with both throttle fully open and without, still read out 90 on all 4.

The Q igniter i did not wire, from searching various places I thought Q45 Ignition Module Igniter 22020 50F00 was plug and play and didn't need to be rewired to work.

CAS is lined up right, my dot was not colored but I have it lined up to the right one. Engine was at TDC, 2nd mark on crankshaft, checked by sticking a long screwdriver down cylinder 1 and felt it go up to the top and back down. Cam gears were off when first did timing with only 9 links between marks, turned cams and matched up dark links with notches on cam gears at 10 and 12. Now have 11 links in between.

It cranks and turns over but does not start. Almost sounds like its not catching. Coil packs are sparking yellow when there suppose to be blue i believe. Tried starter fluid, tried pouring a little gasoline in throttle as well still nothing. Use to get a backfire but don't even get that now.

i would double check my wiring and see if all the wires are intact. did you solder them or just twisted them together? also check your grounds, especially the one from the back of your motor to the firewall or else it won't start.

Everything is solder and heat shrinked. I try tracing wires from coil packs but lose them when it goes through igniter, having a hard time understanding what the igniter does other than amplifying the power. Where should which wire come out. Will check again for grounds.
