stalls while driving

youll need to install a fuel pump pressure gauge so you can see it through the windshield.watch the pressure when it stalls.for pressure loss.

Did that. It is a steady 35 psi
When it dies it increases to 45 psi
And still dies

youll need to check the codes anything else would be a guess.

Checked the codes first. No codes

does it stall while idling or driving?

While idleing Twice it tried to stall while
Driving but because I was into the gas
Pedal all it did was sputter - as if it wasn't getting
Gas. But I know it is getting gas.
Seems electrical

is that the infamous mexican motor? they are known for timing chain issues.

also distributor has sensor that might be intermittant fail?

Timing chain replaced at one hundred 40 thousand
Miles. Also it a 2400 motor.

Distributor is new also. But thanks anyway

Ps my truck is bodydroped 3 inches
With an air ride setup
4 link rear - with the rear bags on the 4 link
Aka cantilever
5 switches 300 psi Nitrogen back up
External fuel tank
n a killer o.g 5 peice train horn
Straight off a freight train
At 200 psi u can hear it 3 miles away
Me and my buddy did all the wrk
Took 7 months for the bodydrop
And have had 3 different bag set ups
First the bags in the rear were over the axle
Rode like a stage coach
Then came the cantilever Rides awsome
However engines I'm not so good with

here's an electrical engine diagram
