starts fine but restart no go
 

Well I have a 94 k1500 5.7 and it's having a starting issue. It will start perfect when cold I can drive it with no problems but it's having restarting issues. When cold I can start it about 2 to 4 times in a row with no problem but after that it cranks and chugs but won't start, tell I let it sit for a couple of mins. I've replaced fuel relay twice, fuel filter, fuel pump, temp sensor by thermostat, oil switch, plugs, both tbi, rebuilt fuel regulator. No check engine but there is a hard code in the ECu, codes or 32,33,34,54. all those have a bad circuit or ecu problems (the manual says) I also want to stat that my ground straps are green and the one with from the fire wall to the block is green and caked with oil. my next step is replacing the ground straps before replacing the ecm. Help please I'm about 600.00 in the hole with this problem

So I'm waiting on a msd pick up coil for distributor 8366 and replacing my ground straps, from to the fire wall and fire wall tho back of the block. If this doesn't fix my starting issue, I'm stuck with my last guess the ecm??

I installed new msd pick up coil and two new ground straps. But my timing is all messed up and it just back fires now so I won't be able to post if the pick up coil fixed the no restart problem I've been having, tell I figure out on getting my timing back In order. If any one has seen this problem before or have an idea if I haven't already, I would appreciate it greatly
