Ok, I need some options. I just got a fuel rail/ pressure regulator and injectors last night from another member of this site. I just got done installing them a little while ago with no success to it starting. Still cranks, but won't start. It has started prior to me installing these fresh parts, but in order to make it start, I had to have someone tap the regulator with a screw driver while I attempted starting. So now I'm lost. I know the spark plugs, wires, distributor cap and rotor could all stand to be replaced, but I know they work. Any ideas???

is your fuel pump working? check fuel pressure

Options:

Swap the motor.
Remove the motor and replace it.
Put a different motor inside it.

Sure you are getting fuel? Check the line coming from the filter to see if you are getting fuel. Getting spark? Check to see if you are getting spark. Compression? If all else fails check compression.

Fuel + Spark + Compression = start. So since the last thing you messed with was fuel, I'd start there. Good luck!

Thanks, I was actually thinking of the compression as that's the issue with my other car, but how would I go about checking compression on this engine which has 2 spark plugs per cylinder? 2 testers? Or just leave one spark plug in with the wire off?
I'm possitive I'm getting fuel. When I removed the hose from the filter to the rail, is squirted out the fuel pressurized within it, and when I zip-tied a parts bag over it to catch any more leaking through, it did have some in it when I removed the bag to hook the hose back up.

are your fuel lines backwards? ive done that lol.

when you do a compression test usually you want to stop the fuel flow. that way you dont fill the cyls with fuel. pull the fuel pump fuse and unplug the distributor. leave the intake plugs in and read fom the exhaust side.

Hmm. I just replaced a bad injector only to find out that the new one was stuck (But for that to happen on multiple of the same set?) , I now know to push on the tips a few times before installation. Before doing that listen to siliva love and check your lines are correct on the regulator, also make sure they are tight and no air is getting into the system.

For pressure testing remove all of the intake OR the exhaust spark plugs (Exhaust will be your best bet for how easy they are to access). then test each cylinder by cranking the car over till the needle stops climbing (usually about 5 cranks). Hope that helps
