injectors are not often bad on these, why do you think that? your pulley bolt could be loose which is essentially free. just got to get it before it takes out the little fins because your timing is based off those

I took it into a shop and they recommended all new injectors and all that. Id do all the repairs myself but I don't fully know my way around the engine since i just got this

dont believe shops. they make their money on markup of parts as well as hourly. I have also heard a ton of techs say they put a super high markup on older vehicles because they dont want to work on them. to a tech the only real problem is tightening a bolt they can only charge you for an hour.

when i didnt have much money and had older cars i had to figure out how to work on these things by myself. i bought manuals for the cars i had, before the convenience of computers and internet forums. anyway you can learn alot by getting a manual for the car, alot of them put notes of how things work and interact and how to test things and not be a parts replacer.

And they also said my PCM is bad forgot to add that.

Yeah for sure they mark up. That'* why I like to do my own stuff, which in my past cars i've had pretty good luck with.

Big difference between a 1999 and a 1990......that'* why I questioned the 3300....

If the car starts and runs fine until you shut it off, and let it sit for awhile, I seriously doubt it'* the injectors.....

However, those ECM'* from '88-'93 were known for problems......I would do a "tap test" on the ECM when the engine is warm and at normal operating temp......

If I remember correctly, you don't even need a puller to remove the harmonic balancer...once the bolt comes off, the balancer pulls off by hand.....you need to check the vanes on the balancer for damage.......however, if the bolt is tight and it is wobbling, you need a new balancer....you need a special tool to align the crank sensor, too....

forgot to mention not to take anything back there again, unless you want to pay for a bunch of stuff not wrong while they figure what is. that was my "parts replacer" comment, except shops do it at your cost, the more they do the more they get

I was only going to let them fix it if it was going to be a reasonable price. I'll try that two test. I installed a different PCM that I have and it didn't really make anything different. Lol

that pulley has fins on the back the pcm uses for timing. the ckp senses the fins and thats how the engine knows what to do, has to be perfectly aligned as tech 2 said and if its hanging out im sure something is misaligned or damaged there.

I find it hard for all 6 injectors to be bad also, I'm sure it'* related to the crank sensor.
