I finally got around to working on my own 3L SVT. I recently installed the 3L. It is a ported 3L with SVT intakes, SVT cams and headers. I tried to start it up and it won't start. It turns over and runs for a second or two but the intake is popping pretty bad.
I run a compression check and all the cylinders seem ok (130-155). Plug wires are in the correct order. I swap to a different set of wires, no change. I swap coil packs, no change. I swap cam and crank sensors, no change.
So I decided to tear it down and check the timing to verify it's timed correctly. I remove the timing chains and re-time everything. The timing didn't seem to be off though. I get everything back together but it still won't start. If I hold the gas all the way down when trying to start I can barely get it running but it's really rough and shuts off right away. The engine seemed to turn over by hand perfectly fine after re-timing it.
I swapped the MAF, no change. I checked the fuel pressure regulator to see if fuel is leaking into the vacuum line and it's fine. I verified all the injectors are squirting fuel. I double checked all the grounds and they are all there. I removed the lower intake and checked all the intake valves and they look normal.
I removed the computer connector last night and the blue rubber piece in the computer is slightly damp so I left the connector off so it could air dry. I also disconnected the harness near the brake booster to inspect it but it looks fine.
Tonight I'll plug the computer harness back on and see what happens. My next avenue of attack is to remove the y pipe and see if there is a clog in the cat.
The only other odd thing I've noticed about this car when I received it is the ground going from the frame near the battery to the transmission tower is severely scorched. I'm not even sure how you could scorch a ground like that unless you hooked it up to the positive terminal. I did run through all the smaller fuses with a DMM and they were good.
The PATs light is working normal, but is there anyway the computer could be fried because of the previous owner. Anyway to verify if a computer is having issues? This is a 1999 SVT Contour. I suppose I'll get a scanner on the car and verify each sensor is outputting.
