Do you have the means to scan for codes

Ask Your Own Chevy Question
Customer reply replied 6 months ago
No one was positive as to what that is. TPS or the one by the pedal. So I changed the TPS.
Chevy Mechanic: Todd Audette, Chevy Technician replied 6 months ago

Do you have cranking rpm on your scan tool while cranking

Ask Your Own Chevy Question
Customer reply replied 6 months ago
I borrowed that one and returned it already. I took the battery out of my other suburban (that runs and starts fine) put it in the bad truck. It cranked faster but no start.
Chevy Mechanic: Todd Audette, Chevy Technician replied 6 months ago

You're going to have to check for cranking rpm

I will opt back in. I see you have a second question going for the same concern. I know you said you have the p1518 code. With the key in the on position is the reduced engine power message displayed on the instrument panel cluster
