Hi all - I'm really stuck getting this car started, and have no idea where to go from here - I know this is a long post but I really need to the advice of some SC vets.
I've researched every thread on the forum I can find on the topic and am still stuck. I really love this car! However, I'm starting to wonder why...
I'll put my questions on top, supporting data below
What should I do / replace next? Some of my last thoughts are...
a) Keep looking for vacuum leaks?
b) Maybe the parts store gave me wrong injectors? Would stock injectors be a certain color?
c) Maybe my "new" MAF / IAC are bad? Is there any way to tell other than buying new ones?
d) Should I compression check the cylinders? Maybe I lost a head gasket? (There are few things in the world I hate more than replacing the plugs on this car)
e) Something else my pea-sized hasn't thought of next...
Now the information...
I'm truly stuck working on my wife's '95 SC, manual tranny. The original engine was getting VERY long in the tooth, so I dropped a crate engine engine in. Despite my objections, my wife asked me to keep everything stock, so I have done my very best to do so.
After dropping the new block in, and having some standard issues, the engine started and ran for my first couple test runs, then I started having troubles, problems included (but not all inclusive), vacuum leaks, stuck injectors, bad sensors, etc...
Regardless, it won't start now - it will turn over and "kick" occasionally and if I pump the pedal it will start momentarily then summarily die. If I disconnect the MAF, I can keep it running if I continuously pump the pedal (although it seems super rich with white smoke / fumes out the tail pipe.)
Here's everything that I've done firewall forward: (at least that I can think of at the moment)
-Crate Long Block
-Rebuilt blower
-New Injectors
-new Fuel Press Reg
-new EGR valve and sensor
-new coolant temp sensor
-new Cam Sensor
-new crank sensor
-new MAF sensor (no- it's not a specialty store MAF)
-new IAC (again, no, not specialty brand)
-new fuel pump
-new plugs
-new DIS
-new CPU
-new clutch
-new flywheel
Testing
-Fuel pressure tests good 35+psi on the rail and takes days to bleed all the way down
-I've looked for vacuum leaks more times than I can count, including pressurizing the lines and practically soaking the engine in soapy water. Under ~5psi pressure, a noticeable 'woosh" is heard when I open the throttle body, which makes me think that there is no longer a huge leak at least...
-The fact that it WILL run makes me think something resembling ignition is present...
- key on engine off tests gives no codes, can't get a engine running test
- can't keep engine running long enough to spray starter fluid on lines for vacuum leak check
Thanks again, everyone - I appreciate any and all help!
