I have 2004 suzuki grand vitara with 120k. Died on the highway while driving.
It has the following symptoms
1. Cranks but no start.
2. When I turn the ignition switch on without cranking the ignition coils get extremely hot after few minutes and start smoking (it has six coils packs, COP) So far I have replaced 3 coils out of six? Is this electrical short? How to trace the short?
2. There is no power to the fuel pump relay from the ECM. When I test the power on the fuel pump relay the test light is dim.

3. The car after I turn the ignition switch on service engine light does not illuminate and nether communicate with OBDII scanner. It shows error link.

When responding please address each question separately.

Thank you
Fred

Had the camshaft sensors replace in my 04 xl-7 after a series of other problems. Truck worked 3 weeks before it broke down again. Was driving and started losing power until truck lost power and died. Now it wont start at all or even turn over. Put a ton in it and tired of it. Need answers and all the mechanics I have been to cant tell me anything. Looking for a cheap fix to get it running to get rid of it. Enough Is enough. Have no idea where to turn

When I try to start the car, all it does it makes a clikcking sound, the light, radio and everything turns on, but it is showing the battery light on. And engine light.

Went to start the car and it just clicked and the linside lights went out. I tried to jump start it and got the same results. Help please.

Brand new battery, maybe 3 months old. Connections look good
