Asked by GuruJ57F1 Jul 25, 2020 at 01:10 AM about the 2003 Chevrolet Suburban 1500 LT 4WD

Question type: Maintenance & Repair

I've replaced the battery, starter and the alternator
in my 2003 chevy suburban 4x4 and it still just
clicks once and won't start. Can anyone throw me
some ideas as to why it still wont start please.

generally speaking if it clicks just once but doesn't start I would aim towards the starter. BUT since you have already changed it, I'd look at cheaper smaller parts. Try your ignition relay. smaller cheaper part. Second idea, starter solenoid, are all connections/ lines clean? Third, crankshaft sensor, another smaller part that is easily ignored ( under but in front of tranny case). good luck
