BOHO Posted November 14, 2009 Report Share Posted November 14, 2009 Is the Haltech supposed to be controlling the timing or is the distributor? Are you getting signal from neg side of coil? Are you getting signal at all? It starts but then shuts off? or doesnt start at all. Link to comment Share on other sites More sharing options...
hiko_seijuuro Posted November 14, 2009 Author Report Share Posted November 14, 2009 yes the haltech is controlling the timing and it starts it runs for like 2 seconds and it dies right now we have the ignition locked at the haltech on 0 tdc and we are playing around with the distributor to see if we could get it runing but nothing we disconnected the vac advance line and nothing either i have been trying to get this cars started and running for almost 2 weeks already but since we have never done this mpi swap before the tunner and me dont know what to look for to fix it.

jahjah Posted November 16, 2009 Report Share Posted November 16, 2009 yah if it starts and dies, you might need to look at some kind of warmup enrichment. Megasquirt has after start and warm up enrichments. i'm sure your haltech does too Link to comment Share on other sites More sharing options...

jahjah Posted November 17, 2009 Report Share Posted November 17, 2009 have ya maybe got something torqued down too hard? like maybe the cam towers are over torqued making it really hard to turn the cam, thus snapping the pin? Link to comment Share on other sites More sharing options...
hiko_seijuuro Posted November 17, 2009 Author Report Share Posted November 17, 2009 well i really dont know what it is the towers were torqued to car specs which is 15lbs everything was put back together to when built to all torque specifications for the car. could the higher compression be the cause for this to happen?

jahjah Posted November 17, 2009 Report Share Posted November 17, 2009 yeah it should be 15ft lbs, how much higher compression? i gotta say i've never heard of nay shearing the pin, are you sure it was completely and correctly installed? Link to comment Share on other sites More sharing options...
questian Posted November 17, 2009 Report Share Posted November 17, 2009 hey man take your plugs out and try turning that machine by hands to see if it turns freely and check that big bolt that holds the cam gear down Link to comment Share on other sites More sharing options...
hiko_seijuuro Posted November 18, 2009 Author Report Share Posted November 18, 2009 well the compresion from the wiseco are 8.0:1 and yes it is all put back together the right way by the book and it still breaks the pin. Questian what should i be looking for in the cam bolt cuz what i can say about it which it is weird to me is that the pin breaks off the cam but the gear and the small front gear for the dist. keep spining with the bolt. and i dont see why the bolt dont tighten with the cam it just keep's spining.
