Hey guys ...I'm a 24 year ASE Technician and did a msd dist install on my 4.3 (w) zr2 blazer.....if I align all the timing marks it will putt on 2 cylinders and idle for 30 seconds and will run (with a 1345) only when advanced 1tooth on dist ...has anyone experienced this ...it was a basket case when I got it with everything tore down to the heads so I didn't pull the factory dist nor hear it run before hand BUT it doesn't miss with tooth advanced but acceleration is very poor so I checked the TPS and it's fine also replaced the spider inj with a Delco upgrade to MPFI. ANY OPINIONS WELCOME!

 

Do you have a scanner that will read cam retard?

 

Yes but it actually has to crank before the scanner can be of use ....

 

So now it does not crank?
