Verona ecm fuse next to fuel pump fuse blows

Ok, so I just put a new engine in my friends 2003-5 verona with the L6 engine. Upon starting the new engine it started and ran for approx 10 minutes, then would not start again. Found blown ecm fuse next to fuel pump fuse in under hood fuse block. replaced fuse and the fuse pops when ign is turned to run/start position. Replaced fuel pump as they share a common power with no change. ECM fuse short to ground somewhere. Any ideas help as I cannot locate the short. Is there a ground or power wire near the starter that shorts this circuit out???

SOURCE: put new pump in tank suzuki vitara v6 petrol being

Hello! I suspect a defective Fuel Tank Pressure Sensor. It is located on the top of the tank...It has a 3 wire connector...Wire colors are...Brown/Red...Gray/Yellow...And Gray/Red...It cost around $260...But it can be tested but difficult to get at unless you drop the tank...Set volt meter to read 5 volts...Using two safety pins, push one into the rear of the in place connector on the outside pin (Brown/Red) and the other on the other outside pin (Gray/Red)...Turn on key...connect meter + probe to the rear right side pin and the - probe to the rear left side pin...Must read +5 volts...Move the right rear pin to the middle wire (Gray/Yellow)...Must read 3.3 volts...If you do not read the proper voltage the sensor is defective...

Why does my ECM-I fuse keeps blowing?


Did you check the crank sensor wire, it may be hitting the hot exhaust. does the wire going to fuel pump have a problem and is shorting out. ECM 1 ..... then there are 5 components that this fuse feeds
1-crank sensor
2- all injectors
3- ECM
4- electronic ignition control module
5- ignition coil - check for a bad wire in these areas. Hope this helps.

Hooked battery terminals backwards


You have reversed the polarity for the CPU in the ECM This causes problems with the program at best and at worst will require a new ECM. Use a scanner to see if the program will reset and if not have the ECM checked for operation. You may have to have the alternator checked as well as reversing polarity blows rectifier diodes.

Caprice classic 1991 model fuel pump will not come on. fuse mounted underhood next to ABS relay blows upon contact with circuit


e fuel pump motor may have failed, causing a short and blowing the fuse. Try unplugging the fuel pump connector at the pump, then turn key on with a new fuse in place. If the fuse blows again, it could be a short in the pump's wiring. If the fuse doesn't blow, it is likely a bad pump.

I have a dawoo matiz car .790cc year 2000.wich keeps blowing the e.c.m fuse and this cuts off the fuel supply. sometimes it starts ok then suddenly it blows again i checked the fuel pump and seems


Check exactly when you do have a blown fuse as you are driving and in turning or as you driving normally. Also check the wires between E.C.M and Engine. The fuel Supply cuts off surely as soon as the E.C.M Fuse is blown because the fuel supply is going through the E .C. M.

1993 Buick Roadmaster keeps on blowing fuel pump/ecm in-line 20 amp fuse. Car stalled out in a parking lot, would not start, no fuel. Changed fuel pump, fuel filter, fuel pump relay. Found fuel pump/ecm...


Sorry to say it could also be a faulty ECM. The ecm uses circuit boards to provide grounds to a bunch of components and can short out internally.
Most of those components can fail and cause the same problem by causing a short "thru" the ECM. Things like injectors, O2 sensors, and so on.
I doubt you will find the problem without a book and some test equipment.

Will not start and checked fuel pump no power to fuel pump i also have blown fuse for ecmb that blows as soon as i replace it


ECM B fuse supplies a constant 12v hot at all times to the VCM/PCM and to the fuel pump relay. The fuse is blowing telling you that there is a short to ground somewhere. Try this, take the fuel pump relay out and put a new fuse in. If it doesn't blow put the relay back in and if it blows then try a new relay. The relay may be shorted to ground internaly. Other wise you'll have to trace the wires to the VCM and the pump relay to look for a chafed wire that's contacting metal. The wire coming from the ECM B fuse is orange and has a splice in it going to the pump relay and the VCM/PCM.
Hope this helps.....Andrew

Blowing ECM-B fuses


The ECM-B fuse is a 20 amp fuse, and you should NEVER put a larger fuse in to try to overcome any problem. The oil pressure switch is a secondary concern; there is an idiot light or oil pressure guage in the dash to alert you to oil pressure problems. Under heavy load, such as towing, your engine requires more fuel, and if your fuel pump is going/has gone bad, it cannot supply the demand.
The problem is almost certainly a fuel pump wire harness short, caused by a dying fuel pump. I have both had this problem myself, and repaired it on three other vehicles. On my vehicle, the wire harness had welded itself together when the fuel pump locked up, and the wire harness caught on fire.
The fuel pump is in the gas tank (of course my tank was full), and the tank has to be dropped to access it. The wire harness is modular, with plugs at both ends, and can be bought from the Chevrolet or GMC dealer.
If you put an incorrectly-rated fuse anywhere in your vehicle's electrical system, the WORST place to do it is where you have--the fuel pump circuit. Fuses blow for a reason, and the manufacturer's engineers properly size the fuses for the application at hand. Please don't do that again.
This can be a very dangerous problem and repair, and no, it is not cheap.
Do not attempt to operate this vehicle until you have had the problem properly corrected. Good luck.

Blowing ECM-B fuses


The first thing you should do is to locate the oil pressure switch/sending unit.


This switch serves two functions.

1) provide oil pressure reading

2) disable the fuel pump relay in event of oil pressure loss.

===

When this switch is failing to provide the correct pressure to the ECU. The wiring harness can overheat and eventually create a short.

ECM B blow is because the harness is grounding/shorting.

===

DO NOT drive the truck until you change the oil pressure switch.

After you change the switch,you should spend sometime to inspect the wiring between the fuel pump relay,ECU and fuel pump.


Please post up day on the comment window/page.

I will follow up on it later.


Good luck.
