My 1998 eclipse wont start... changed plugs and wires and charged battery and still nothing.... cranks three times and tries to start but nothing. What next?

SOURCE: 1990 Mazda 626 wont start

check battery voltage,if good, check main fuse & relay

SOURCE: 1998 Jeep Cherokee - hard to start

My 98 Cherokee was the exact same. I used to have to turn the key back and forth 3 times and then it would start. Otherwise it would just crank and crank for a while and then start. Pretty embarrassing! Took it to the dealer and they said that my fuel pump was losing pressure. I changed the fuel pump and I don't have to prime the pump anymore.

The s10 have a fuel shut off relay to shut off fuel supply in case of an accident. They also have a anti-theft system that prevents fuel in case of theft.Pull the fuel line off and crank the engine to see if you get fuel. Sorry I can't be of more help but without hands on vehicle it is hard to tell.Also your fuel pump maybe sounding like it is pumping. In other words it may be running but not pumping fuel it mat have a ruptured diaphragm in the pump.The pump is running but not pumping fuel. Pull the fuel line off at the fuel filter and turn on ignmition or crank the engine you should have about 50PSI coming out.If you don't install new fuel pump.These vehicles are common for this problem the fuel pump runs but does not pump fuel or not enough pressure these vehicle require 57 PSI to start if it has less than 51PSI it will not start unless you use starting fluid then it will run.It will run with less fuel pressure it will just not start with less than 57PSI.

Hope this helps

Hi,

This is how your problem is solved in my shop. Out of the box, I'd say that you have a problem with the fuel management system. However, there's a good chance that it's something simple and inexpensive like a clogged fuel filter or water in the fuel tank.

My second area of concern would be the manifold pressure sensor which is loctated under the hood, center, rear engine area, above valve cover, mounted in bracket. However, you must remember that these nothing more than starting points and not guaranteed solutions.

First a little background for your edification. You may be aware of all this but we've never done business before and all assumptions are off the table.

For an engine - make that any engine and irrespective of manufacturer - to run, you need three things to happen inside the engine, compression, fuel and ignition, without any one of these components the engine will not run.

• Compression - Engine compression caused by crankshaft rotation and pistons moving up and down inside the engine block. If the timing belt or timing chain fails it will cause the camshaft to become out of correlation with the crankshaft or allow the camshaft to stop rotating. Either of these conditions will cause the engine to lose compression and sometimes cause internal engine damage.
• Fuel Delivery System - The fuel system includes: fuel pump, fuel injectors, pressure regulator, fuel filter and pressure lines. This system is used to supply fuel under pressure to the fuel injection system, the lack of fuel pressure or volume will cause the fuel delivery system to fail and the engine to stall or not start.
• Ignition Spark Delivery System - The ignition system components include: spark plugs, spark plug wires, distributor (if applicable), crankshaft angle sensor, camshaft angle sensor, ignition coil, ignition module, knock sensor and PCM (powertrain control module). The engine relies on the ignition spark to be delivered to the combustion camber at the correct time. If the ignition spark stops or is delivered at the wrong time the engine will not run or run poorly.

Whenever your engine cranks but does not start, runs rough, staggers, sags or cuts off, follow this Troubleshooting Guide. Some of these steps require a code scanner. They are costly but AutoZone will loan you one for FREE.

Most vehicles operate by the same principle; basic troubleshooting procedures apply to most cars.

• Step 1: Anytime you have a problem with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system, Air Bag) inspect all fuses using a test light and check the under hood power distribution center and under dash fuse panels. If all fuses test okay continue to the next step.
• Step 2: To check for problems with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system, Air Bag) and the fuses test okay a trouble code scan is needed to identify any system trouble. Use a simple scanner tool to retrieve trouble codes and see if they relate to the specific problem, like a crank angle sensor failure code. If the trouble code present does not pertain to the immediate problem like an EVAP code ignore it until a later time, after the car is running.

The reason we repair non-related codes after the engine is running is because sometime false codes can be triggered by the engine not running. Once the engine is running again the code present might cycle and turn itself off. You might say "if the engine doesn't run shouldn't it have a trouble code?" Sometimes conditions occur that will not be detected by the computer, example: if the fuel pump fails the computer cannot detect the failure, so the engine doesn't start and the computer thinks everything is okay with no codes. If no trouble codes are present proceed to the next step.

If you have trouble using the code scanner or interpreting the codes click on the following link and use my access code (carrepair): Free Automotive Repair information for Users of a Code Scanner www.repairpath.com

All the best

have diagnostic codes checked to see if you have a cam or crank sensor fault. make sure fuel pressure is at the required pressure, just testing to see if you have fuel at the valve is not enough. replace all spark plug wires. if you replaced two then all are just as old and even when they "look good" does not qualify as "they are good". Replace coil pack. start up drive away happy
