I got a 87 pick up I'm working on. put a new engine in it but can't seem to get it fired up. I get fuel and spark I even went as far as replacing the coil with an Accel one. Timing is correct also. All sensors are plugged up correctly. One thing I didn't do was replace the upper intake manifold and throttle body gaskets. Could that be a problem? I've seen them run before without replacing them. I'm pretty much stumped! I've tried everything to my Knowledge. Anyone ever run into this problem? Any feed back or tips would be very helpful. TIA!

 

Three ideas:

1) check that all your grounds are hooked up. There is one on the intake plenum and I have had that mess with my head before.

2) are you *SURE* the timing isn't out 180 degrees?

3) if the truck has been sitting for a long time, you may have crummy gas in the tank. Probably not the case, but I thought I'd throw that out there.

 

I never touched the timing chain I bought the motor from a guy who is a toyota tech. he had it sitting for a year and decided not to build another rig I checked the marking on the crank pulley @ the zero mark and matched it up with the rotor in the distributor to fire the # 1 piston @ TDC. Could that be something? Also I noticed my ecu has a sticker on it that says 22r ?

 

Are you talking bout Cranking it 180 degrees and then setting the rotor up again to TDC ( #1 piston)??

 

Maybe someone with a few more 22re builds under their belt can chime in here...

 

Thanx though!

 

I would start by asking the guy you bought it from to help you out. Your ecu says 22r. What motor do you have? A second person can help a lot with timing issues. Sounds like you have timing issues. Best wishes

 

I bet your timing is out 180. You have to make sure that the #1 piston is at the top of the compression stroke. Pull your spark plugs and put your finger over the hole on the first cylinder. Then turn the motor over by hand until you feel compression. Once you start to feel compression keep turning the motor over until the dot on the crank pulley lines up with the zero mark on the oil pump. Now that you are TDC pull the distributor cap and the rotor should be facing directly at the mark on the distributor housing. If it is off then pull out the distributor and turn the rotor so it is facing straight up. With the rotor in the 12:00 position push the distributor back in and it will turn counter clockwise to about the 10:30 position. Your rotor will then line up with the mark on the distributor housing and your timing will be correct. You still will have to adjust the timing once you get it running. Also make sure your plug wires are on correctly. Hopefully that is all it takes and let us know if you still need more help.

 

I'll throw this into the works. Check the valve lash. Believe it or not I have seen people rebuild and engine and don't care to set the lash and it gives cylinders low or no compression, causing the engine to run poorly, if at all.

cough, cough, previous owner of my truck, cough

 

Thanx fellas will give her another try! I'll keep ya'll posted!

 

thanx to all that replied my timing was 180 off stupid me i swear i double checked i guess them miller lite's were kicking in! LOL!

 

glad to hear ya got it running.
