1990 CV Wagon Cranks but No Start

[Freshmeat]

Yeah. I pulled the vacuum from the MAP, but didn't actually unplug it. I'll grab a spare from the '89 at the Mustang shop when I get the ECM. Supposedly it ran great before he killed it.

I'll get that ECM and the MAP.
If neither fixes this thing, I'm tearing straight down to the timing chain.
If the timing didn't jump, I'm taking it to a shop. I'm done. I'd have been waaay better off having it professionally diagnosed for $85 by now, but it's gone past wanting to figure it out myself. Now I just want it fixed. I have a ported Trick Flow R intake on its way to my house, along with a complete "factory CAI" set-up in the front seat, 3G swap kit on my kitchen table, cylinder heads on my F150 passenger floorboard, and a set of 2008 Mustang GT 18s coming this weekend. I thought this would be a speed bump on the road to having a fun car, but this is really killing me right now and I want it fixed.

89 Mustangs don't have a MAP, they have a BAP. Same damn thing, but the BAP doesn't have a hose barb on it usually. If its got a hose nipple though, you're good to go.

No, he has a '89 CV that he took in as a C4C. Said I can have the ECM and anything else.

[85crownHPP]

Yeah smack the IAC a couple times to make sure its not that... if the IAC is stuck in the wrong place it wont start even if you have gas and spark.

my town car refused to start in 2004 after i installed the new engine.......i replaced the tps and it fired right up......never had a problem with the orig motor not starting

[Freshmeat]

On my way home with MAP, ECM, and ignition coil from a known running 89 CV. It didn't die even after the liquid glass stuff was ran through it.

Oh- and he gave me an aluminum driveshaft from a CVPI he had.

[johnunit]

sounds like a sweet deal man. Good luck.

[Freshmeat]

It's alive!

The final straw was the ignition coil of all things. Thain was the only one pushing for it at any point, but I'd have sworn it had good spark... but sure enough, that's all I swapped tonight and it fired right up.

I still need to add antifreeze and establish the timing, now, but it's running! It smoked its ass off the whole time. I can only imagine how much gas is built up in the exhaust system right now.

[import convert]

have you checked to make sure the coil is working right

[87gtVIC]

:headbang: Now the real fun starts.

[Freshmeat]

I stand corrected, Sir!

In my defense, though, the spark really did look great! I only even swapped the coil because this one had a brass barb!

[gabegt90]

glad to here woody nice to see you got the wagon running again

[Brandon]

Glad you finally got it running... I bet that was a big relief.

understandable. its hard to believe that certain things could cause and engine to start. you end up thinking big expensive fixes instead of simple.

the big thing is to jump a plug gap you only need about 5k-7k volts which is easy for a coil. youd need to test it with a bigger gap to make sure its bad. most spark testers will have a 25k volt gap to make sure it puts out more then enough spark.

but all in all it runs and thats the important thing. good work
