Can be - but I'd put injectors on 'position 31' on the suspect list.

Check batt voltage. Make sure also ECU gets ground and +12.5V. See link below.

First and easy tst: try unplugging MAF. Shorted MAF can 'kill' engine. After unplugging it will start in safemode - if...

See also for campos signal from distributor (on my CDomain page 9 & 10.)

Note that long cranking (nostart) will get plugs wet as all injectors pump simultaneously. Plugs have to be cleaned or must have long dry-waiting period or crank-dry with disconnected injectors.

If belt jumps, engine cranks and about starts - but will not. Check the belt and its tightness. WHEN was it replaced? Should be once in 5 yrs 60k miles...

Pls tell how it goes.
