Hello.

The water pump on my B3000 recently blew up. Upon replacing it, and the water temp sensor, I have encountered a crank/no start.

Diagnostics so far:

Battery was ancient - replaced with new.

Fuel pump comes on during key on, fuel pressure good at Schrader on rail.

Battery voltage shown at +12v (red wire) on coil pack supply plug when key on/engine off.

Spark test good on plug end of all 6 plug wires using old school spark tester (not the window type). Large, white-hot sparks.

Plugs wet after crank. Plugs questionable. Replaced with new.

No codes. ODB reader shows 156-158 RPM at crank.

No CEL/no THEFT during crank. THEFT blinks slowly when key on/engine off.

Fuses and relays checked with meter. PCM relay and blower relay swapped in case of fault under load. No change.

Where do I go from here?

 

Disconnect MAF and see if it starts. If not check compression on a few cylinders. If they're low but about equal check to see if timing chain slipped.
