JerryB Posted June 26, 2016 Share Posted June 26, 2016 I have a 1998 CH w/350 in it that spins over good but won't start. Has plenty of supply fuel pressure but nothing going to injectors from pump. It ran fine into wash bay but after its bath it don't want to go. I've cleaned all wiring harness junctions and cleaned engine to rail ground strap but its a no go. Is there a fuel shut off selonoid or relay somewhere I'm missing? Could something have gotten wet in the electrical system? This is the first time in 1.7 million miles she's failed to go.

fjh Posted June 26, 2016 Share Posted June 26, 2016 (edited) If you haven't got it running yet , All I can suggest is blowing everything off and checking the ecu fuse Edited June 26, 2016 by fjh Quote Link to comment https://www.bigmacktrucks.com/topic/45791-350-wont-start/#findComment-337618 Share on other sites More sharing options...
41chevy Posted June 27, 2016 Share Posted June 27, 2016 The ECU controls the injectors The VECU module as well that can cause problems. if it got wet, wet connectors or worse. Where it is located on your 98 don't know.

JerryB Posted July 1, 2016 Author Share Posted July 1, 2016 Okay thanks guys I had to make a round with another truck and haven't got back to my problem child yet. I was thinking it has to be something with the ECM so I'll take your advice and check the fuse and module. If that doesn't work I'll carry the ECM to the hospital to get it checked.

JerryB Posted July 3, 2016 Author Share Posted July 3, 2016 Finally had a minute to check it out. Connections good, ECM good, ECM fuse good but still no start. Took wires off and cleaned the in dash selonoid and fuse panel connections and it starts like new again. I'm a happy camper again. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/45791-350-wont-start/#findComment-338253 Share on other sites More sharing options...
fjh Posted July 4, 2016 Share Posted July 4, 2016 Good find bro it's a pain when unrelated crap happens. After a simple wash down down right annoying just a imagine spending hundreds of dollars towing it a bunch of hours shop time for a guy to chase that down giving the info we had to work with! Totally heading the wrong direction for hours then to fine that. good find bud! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/45791-350-wont-start/#findComment-338417 Share on other sites More sharing options...
