Question about 2003 Chevrolet Silverado 1500

2 Answers

'03 Silverado 1500 wouldn't start, battery 6 yrs old, replaced it, now starts, but when put in reverse or drive, voltage gauge drops way down & truck dies after going about 5 feet. Had alternator tested, it's good. What's the problem?

    normal voltage is between 14 and 15 - when I put the truck in reverse or drive the voltage drops down to about 10 or 11 and the truck dies. Here's what happened in order:



    1. Truck didn't start - battery 6 yrs old (6 yr battery) - changed it & truck started

    2. Took cable off of battery to see if it would die while running to check for alternator problem - didn't die

    3. Took alternator off - had it tested just to be sure, but it's fine.

    4. Now I don't know what else would cause the volts to drop. A few days before this happened you could see the voltage gauge move slightly down & then back up again.



    Any idea?

    Also, engine sputters & stalls out. Idle sounds don't sound normal in park or in drive & reverse. It sounds really low.

Get the codes read on this vehicle (AutoZone will do it for free). If I had to guess, it is probably a sensor, most likely the crank position sensor that needs to be replaced. Make sure you get them read when you try to put it into drive. Let me know what you find out with the code reader.

Check your fuel pressure it should be 60-66 psi with key on engine off.If its not within these specs then replace the fuel pump and filter.Sounds like the pump might be weak.

I have a 2003 Chevy Silverado 2500. Once again, it wouldn't start. The battery was completely dead, and it would not even start with a jump. Replaced the battery, started fine. But, now the voltage...


Battery was completely dead ? after how long , over night , or just out of the blue ? These year GM vehicle's 03 to 06 have instrument cluster problems , draining the battery . Do you know what parasitic draw is ? Google it . They used lead free solder constructing the electronics , an after a while it causes silver migration .

In march tuck wouldn't start mechanic replaced alternator truck ran good, battery light stayed on had test done at O'reillies Last week drove to Port Aurthur & on the way back gauges stopped...


You need to get a digtal voltage meter (about $15) and check it out yourself-readings at the battery should be 12.5 volts after sitting overnight. Once you start it, the readings at the battery terminals should go up to almost 15 volts when first started, then gradually drop down to around 14.2 volts-I would bet either your battery is bad, or your battery is bad and your alternator has failed trying to supply power to a bad battery-either way, your mechanic should not have allowed the battery light to stay on after changing out the alternator without finding out what was wrong-he did not fix it.

99 silverado charging problem


the problem could be a bad connection somewhere in the wiring or the voltage regulator, it should be charging between 13.8 & 14.3 volts, it should be constant not up & down.....hope this helps.....cheers

98silverado 1500 does not want to start in the am


it sounds like you need to replace your battery.jumping it to get it started will charge the battery especially if you are driving it around and will hold charge for a bit.but if truck is sitting all night then battery is just draining

03 silverado revs on 2-3 shift, light acceleration


Check TPS for smooth and linear electrical response over the entire range of motion. If not, replace.

Double check by using the pressure gauge and watch for a big drop when the PCM commands 2nd gear. Worst case: poor line pressure rise. Poor line pressure rise due to leaking boost valve, clogged EPC filter screen, failing EPC solenoid, or worst case: leaky seals throughout. Transgo HD2-C kit fixes first two without removing trans. Seal restorer may fix last problem, but probably R&R. Also try a transmission flush with BG brand products (Firestone stocks it).

Put a line pressure gauge ($55 shipped on Ebay, or visit a local trans shop) on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.500" boost valve (easy fix in pan).

Good luck and hope this helps get more life out of your transmission, but start with the simple and check the TPS and replace if worn.

I have a 03 chevy 2500HD the amps and rpms go down when putting drive and reverse and pulling out from a stop. Battery went bad changed it now this problem started thanks a little puzzled


First, make certain that the battery you replaced is fully charged and that cable connectors are clean and wires are in good condition. Sometimes after sitting on a shelf , they aren't fully charged when you buy them. Your alternator can never charge the battery, it's designed to maintain the state of charge. You may be used to seeing readings that reflect your charging systems efforts to keep a failing battery charged. Those readings are not normal.
Your charging rate does change with engine rpm's up to a point...then the regulator takes over. Rpm's generally do drop a bit when in gear, and obviously change when accelerating from a stop. All your instruments are actually volt meters with different scales on them all rely upon actual line voltage to operate and though this is not as noticable as at a volt meter or amp meter, there subtle changes in all readings. Providing that you are getting proper voltage at the battery (generally 13.5-14.0 volts at the battery with engine running with accessories on) I would not worry about it. You can get your charging system tested at most larger parts stores free.
This isn't a fix, but rather an explanation as to what you may be seeing. If within normal range it's OK.
