a heads cam and intake package is what i did and at the same time replaced the opti wires and plugs. i tried to crank today and it didnt happen it would only turnover. here is what i checked and still same result

double checked wires and plugs and coil.
i checked fuel pressure and it was plenty high
i checked injectors with a light pluged into harness they were working
i checked compression and it was plenty high
i checked spark with tool between plug and wire its getting spark

i have no idea can you help

mechanic told me to check every cylinder for compression to rule out timing chain errors and if each cylinder has compression that rules out bent pushrod from coil bind and the chain.

also he said the only other thing could be bad opti or opti was not installed right something with the clover leaf thing???

 

Might be a problem there. When I did my head-cam combo put the car together and it wouldn't run right. Ripped it apart to double check everthing, everything was correct, put it back together and it started right up no problem.

I know its not what you want to hear, but it sounds like all you have left is to take it back apart and double check everything to make sure its all installed correctly. It doens't take much to throw things off..

 

well i guess if the front has to come off not to bad but as long as heads and intake dont i will live ! can the opti actually go on wrong?? i mean im lost!

 

Does it turn over easily? WHat are some more symtoms? Does it cough through the intake. Be as detailed as possible so we can help you.

 

turns over easily a little noticeable pops out the exhaust . i also tried shooting some ether starting fluid through the tb and that made more bigger pops from the exhaust but thats about it. almost sounds like burps from the open headers . i can remember plain as day that i was dot to dot on the chain.

 

can opti be installed wrong?

 

Yes the opti may be installed wrong. Did it fit right in its hole. It should of gone right in. I had a hell of a time with my cam swap because I swore everything was in right, when I pulled the opti, I could see that the pin on the cam was not positioned wrong so I fixed it. I havent had a problem since.

 

Quite easily especially on the vented optis. Much harder to screw up on the 93/94s.

Ask me how I know. And we had a blower in the way.

How did you adjust the rocker arms? I only ask as a couple times I went to check buddies head swap jobs and the rockers were all too loose, engine turns over real easy and dont start

 

I adjusted my rockers on the wrong cylinder the first time I did mine. Just something to think about.

 

i had my mechanic adjust the valves for me so i know im fine there!

i guess the only thing left to do is check compression and if its all good then it has to be that the opti was installed wrong??

 

First if he adjusted the valves, he SHOULD have seen a problem with valves not moving or bent rods.
You also said you checked compression once already
You may be right about the opti installed wrong. If you have spark and you squirt fuel in the intake, elminating any fuel supply issue, and it doesn't hit. The spark must be occuring at the wrong time.

Crank her around by hand with #1 plug out. When it starts to push air out the cylinder, put a wooden dowel or pencil in the cylinder and line up #1 to TDC. Then pull the cap off the opti and see if the rotor is lined up with the location of the contact for #1 cylinder on the cap.

 

The otpi can easily be installed wrong as it's a blind mate of the drive pin to the "drive hole". When properly installed the opti's 3 mounting tabs should be flush to the timing chain cover. If you loosen the mounting bolts and the opti pushes away from the timing cover (about 1/4") then the pin's in the wrong place. Just helped by buddy solve the same no start issue...opti installed wrong!

 

the valves were adjusted before we turned it over to start so are you saying that if it was the chainthen spinning it would have told us that ?
the opti i really dont remember i just stuck it on and tightened it up i didnt know it could go on wrong. well i guess leaning more and more towards opti! DAMN

 

In the process of adjusting the valves, you have to watch what each valve is doing to get the one you want to adjust on the correct base circle point. So you have to rotate the engine.

You already did a compression test. So you said.

If you have fuel unquestionably and it's not evening trying to start, it is out of spark time. That coupled with the "i really dont remember i just stuck it on and tightened it up" factor and here's your sign.

The question is, is the fuel unquestionable. Pressure and pulses, maybe. Squirting fuel in the intake, unquestionable.

Put a cylinder on TDC and check the position of the rotor. Guaranteed it's not timed correctly. I'll bet the seal is folded over too.
