Troubleshooting No-Start Vehicle Problems

There is nothing more infuriating than getting into your car only to find out that it would not start. As with other vehicle problems, the causes could range from a mere nuisance to major repairs. However, every driver must know the root cause of the problem and to give it a timely solution.

Murphy’s Law describes all about such situations: whatever can go wrong will go wrong, and at the worst possible time. No start problem could happen when you are already late for work or the car is 200 degrees below zero out. Now, that makes you even more infuriated and you realize that indeed anything that can go wrong will go wrong.

Troubleshooting no start problems would be easy if drivers know its causes. There are common causes and reasons behind the problem. The first reason is the failure of fuel pump failure or the restriction of fuel filter. This is the most prevalent cause of no-start problems in recent times. This is primarily due to the negligence of vehicle owners to enforce scheduled maintenance. Said negligence could be mirrored in part by not having the fuel filter changed at right intervals. Some fuel filters cost $100.00 however in vehicles like the Jeep Grand Cherokees which was built in the late 90s, replacement of fuel pump could cost about $800.00! How many times do you want to spend that much?

One significant cause for premature fuel pump failure is when the driver allows the fuel level to go lower than ¼ tank for extended periods or running completely out of fuel. This will make the electric fuel pump to run dry, which eventually destroys the pump. GMs Vortec engines - 4.3L, 5.7L with the CPI fuel injection system – fail in many ways. Some of the ways include plastic tubes leak, fuel pressure regulator leak, and when poppets get plugged.

No start problem could also be attributed to timing belt failure or timing belt tensioner failure. Basically, timing belts are engineered to last approximately 40,000-60,000 miles under normal use. If these belts break, it could result to engine damage. But for vehicles manufactured by Acura, Honda, Mitsubishi, and Nissan brands, the repairs would not be so costly. Moreover, it is recommended that the timing belt be changed at regular intervals. The tensioner should be replaced if questionable.

Another root cause of no start problems is distributor failure. When your vehicle breaks down without any warning - that could be an indication of the problem. Other symptoms include history of intermittent breakdown and intermittent failure to start from cold, which may be caused by security system failure. Mitsubishi electric distributors in the Ford Probe and Mazda vehicles have a high failure rate.

Electrical trouble is another cause of no-start problem. Ford ignition switches, manufactured in the early 90s, have been known to cause fires. Hence, every driver must check them regularly to shun future bother. One should not only focus on Volvo distributor rotor or Land Rover brake pads; he must inspect every auto part to ensure that it is in working condition.

Batteries, clamps and cables could also cause no start problems. Drivers and owners alike oftentimes neglect corroded batteries. The fact is, batteries do not last forever; do not confuse them with diamonds. Moreover, poor maintenance could result to battery failures that lead to other vehicle problems.

ECM/ PCM failure is also a no-start cause. This problem is common to GM products manufactured on mid 80s. Other causes include inaccurate fuel gauges, lack of oil, plugged exhaust systems, bad fuel injectors, and worn flywheel.

  1. Hi there everyone of you.!I have this 1995 chevy astrovan with this engine{producer code GMPT,4.3L V6 CPI L35}Problem is that when engine is cold on mornings,i'm going to start it and runs but erratically producing vivrations,black smoke and sometimes blue too,it is trying to stay runing and then when reaches the normal operating temperture,the erratically knocking disappear,someone has told me,it probably have something to do with the ignition coil,a cloged fuel filter and make some test on plugs wires,but I believe that has to do with something but that those suggestions.also the mechanic makes some engine analizer scanner to verify any kind of hiden or recorded codes,but it shows nothing abnormal.Can you please think about this and give me some advice,i understand that GM,desingned a single CIP fuel injection that supply fuel using some tubes with poppets that gets pluged and problem is greatly reduced with some engine normal opperatig heat.Many thanks to you for any knowledge or advice provided to finish this.Mervyl Figueroa,Toa Baja Puerto Rico.

  2. I leave your comment here to solve what you consider as one of major problem to your car.From those what you have reffered to mechanics is just another thing to get better firing,but for me as a mechanic I would say that it something to do with your valve cylinder(tappet),adjust it to the correct ratio for air and fuel to start the engine ,I am not sure for your chevy astrovan tappet ratio,i tink you can refer the chevy books or mechanics,But to make sure the operating heat would really clear the problem,adjust the cylinder valve.
