Ok, so I had some problems after a cam install in my nightmare of a car... I spent quite a bit of time taking off the front dress on my motor to check and see if my timing chain snapped... not the problem.. chased it down to a fusable link... scary how easy it actually was... Now tht I've put everything back together, when I put the key in and turn it to ON, the injectors start firing, and the tach reads around 900 rpms... but the engine isn't running...
Clicks hard, as if the starter were bad... will get that checked out tomorrow when the shop opens, other than that, just some seriously screwy electrical ghosts...

Can someone please tell me where I screwed up my wiring? I need to get the car running, I'm paying for the stall where I work on it...

BTW-90 mustang GT 5 spd, X303 cam, comp cams dual coil valve springs, hurst short throw shifter, FRPP shorty headers. in case any of that matters.

Please help, I'm pretty desperate here...

Check the upper/lower intakes for pinched wires, also make sure the ground on the intake is connected.. good luck chris

Next time if you think your timing chain has snapped, take your distributor cap off and turn the motor over with the starter and watch the rotor. If the rotor turns, timing chain is working, if not turning - broke.

If you are getting fuel from the injectors and it won't start then you must not be getting spark, at least not at the right time. Try to trace that out.

If the starter clicks hard, check and make sure the starter is bolted in good and tight.

Good luck, don't give up !

If you think your timing chain has snapped, DONT turn the engine over or you might hear BANG as a piston comes up to meet a still open valve. Turn it over using a breaker bar on the crank pulley bolt.

You have a 12v shorted to ground, giving some voltage into the cluster. If a FL blew, you must have had a major surge. You probably have a whole clump of wires all melted together at some point in the harness. Nothing to do but start unpacking the factory harnesses. If you have an assistant, you can do a "goose test". Have someone sit and watch you tach. Then walk around squeezing and flexing harnesses. When you squeeze the problem area, the tach will wiggle.

Ford 5.0 = non-interference engine (unless it's been modified). Even our 24-Valve DOHC V6 in the SHO in a non-interference engine.

REALLY?!? Neat! I learn something every day. I guess 1.7 roller rockers would count as having changed something though....
