Running great then dies(03 Navig. continued)

[Shad]

It has done this twice now…

Common issue is running well, idles down, runs well, begins to run less well, push the gas, it dies, won’t start.

I have spark, fuel pressure 39lbs, checked the inertia switch circuit around 10 volts, changed brake switch, checked relays and fuses, checked connections to injectors and coils. Now cleaning the MAF sensor, left fuel gauge on for ten minutes it held pressure.

Any ideas

ok I was able to check the kv output from the coils… I had 10kv on each

I need to find out where I would find the spec output for each coil as Eric thought that it would probably be no less than 40kv, but it would not give me 40kv on any coils

One coil was unable to do 10kv I disassembled and reassembled the spring making sure it had good connectivity it gave me 10kv but the spark was much less than the others, I threw it away

Battery was at 12.5v when I started, charged it and started again to eliminate that variable.

WHERE DO I FIND THE SPEC. voltage FOR THE COILS?
