umm so i put a new engine in my bronco, the block is from a 89' mercury car, 5.0 HO, i used every part from my old engine because it was blown. everything is hooked up right and the plugs are firing, but all its doing is turning over and not starting. plugs are in the right order and the distributor was reset like you supposed to but still nothing. what am i doing wrong??

Sounds like a fuel delivery problem. Make sure you have fuel pressure and that your injectors are firing. you can hook up a little light bulb on a jumper wire to one of your injector connectors and it should flash when the engine is cranking.

check your valves souds like they may be tightend down to much keeping them open. which will cause a loss of compression if you have a haynes manual it is this procedure is on pg 2d-29 i dont have time to type out the whole process

and you do know that the 5.0l HO has a different firing order than the 302 that came in our bronco?

Cylinder numbering

The table below covers the positions and numbering for all cylinders on a windsor motor. Generally, it can be summarised as follows: When looking into the engine bay the number one cylinder should be on your left hand side (left bank) at the front of the engine. The number eight cylinder is on the rear right (right bank) up against the firewall.

it should you used all the parts from your original motor, and just the HO block, which is prolly just a plain jane 302... had you used a complete HO engine your camshaft and firing order would be different... it was late last night and I thought you had transplanted the whole enchilada in there...

thats about as vague as me saying I am having trouble breathing... need more information... will shift lever move? have you verified all your linkage is together? can you manually move the lever on the tranny itself? the more info you can provide us, the better we can help narrow it down... and everybody loves pics... so some of the linkage to your tranny might help someone if thats your problem...
