- Electric fuel pump failure /fuel filter
restriction
One of the most common no-start problems I
have seen in recent times is the failure of in-tank electric fuel pumps,
primarily due to lack of proper scheduled maintain on the vehicle owners
part of not having the fuel filter changed at the proper intervals, sure
some fuel filters can cost approx. $100.00 and up to replace several times a
year but in some vehicles such as late 90s Jeep Gran Cherokees replacing the
fuel pump costs nearly $800.00! How many times do you want to pay that?
Also another cause for premature fuel pump
failure is allowing the fuel level to get to below ¼ tank and below for
extended periods or running completely out of fuel running out of fuel
allows the electric fuel pump to run "dry" which nearly
immediately ruins the pump.
Vortec Design GM engines 4.3L, 5.7L with the
CPI fuel injection system the CPI unit fails in many different ways; the
plastic tubes leak, the "poppets get plugged, the fuel pressure
regulator leaks.
- Timing Belt Failure / Timing belt tensioner
failure
Timing belts are designed to last approx.
40,000-60,000 miles under normal use not changing the timing belt before it
"breaks" can result in expensive engine damage in some vehicles,
such as Honda, Acura, Nissan, and Mitsubishi. Always have the timing belt
changed a little before the recommended change interval and check the
tensioner replace if questionable. Timing belt tensioner failure is common.
- Distributor Failure / Including Ignition
control modules
Mid 80s Gm 4 cyl. V-6s
Most all GMs with Electronic distributor 4,
cylinder, V-6, V-8 1988-1998)
80s / 90s Ford TFI ignition (grey module
bolted to outside of distributor)
Ford Pick-up assemblies inside the
distributor
I have seen many distributor failures on
Hondas especially due to bearing failure.
- ECM/ PCM Failure (computer)
- Primarily on mid 80s GM products with 2.8L
engines and "W" in the 8th position of the VIN #
- Alternators
Most problem alternator I have seen is the
CS130 /CS130D on some mid 80s GMs for the CS130 and on later GMs the CS130D
on like 92 and later makes like Gran Am, Gran Prix, etc.
- Crank / Cam Sensors
Late model 92-93 Chrysler vehicles with 3.3L
engine Caravan, Voyager,
Mid 80s GMs 2.0L crank sensors 2.5 L crank
sensors
Mid 80s- early 90s GM V-6s crank sensors
90s Jeeps 4.0L engines cam/ crank sensors
Mitsubishi Galant 4 cyl engines crank sensors
(failure due to balance belt failure and broken belt cuts sensor wires and
damages sensor)
- Batteries/ Cables /Clamps
Many neglected corroded Batteries find their
way to our facility; Batteries do not last forever! Poor Maintenance
practices cause many many battery failures which often leads to other
problems.
- Electrical Problems
Ford ignition switches, in escorts in the
early 90s the electrical portion of the ignition switch will separate
inside, some ford ignition switches have been known to cause fires!
