It sounds like the water pump is weak

The long warm up suggests the thermostat has failed and is stuck open. The hard cold start is commonly caused by a faulty coolant temp sensor or the wiring connector on it. The idle surging can often be fixed by disassembling the throttle body and cleaning out the carbon build up. Be aware that the throttle body idle control box also has some internal gears that strip, also causing surge.

The radiator and thermostat do not keep the car from running.. If you overheated the engine.. That could keep it from running.. Post a comment and tell us if the engine cranks over and will not start OR it will not crank over..??

you have a boostleak, i build gsx's my roommate owns 4g63 power, give me your email er cell and i will send you a boost leak detector you hook up to the turbo inlet and shoot pressurized air into it and if you have a boostleak it will leak out of the engine somewhere that is your leak you replace the seal or hose and blauw the car is fixed, hook me up with blue feedback since im going this far out of my way. the reason you cant get past 2500rpm is because unmeetered air is being let in post maf sensor and the ecu is trying to richen up the engine which is causing the black smoke and probably a strong smell of fuel. my current dsm is the 9th one ive owned =) they break alot lol easy fix though.

turm on the turn signals andremove the flasher that is buzzing and replace it it is not a fuse

This is a problem with the main ECM (Engine Control Module). Similarily, the early sebrings and avengers shared the same engine as the eclipse. When the vehicle fails to start, try disconnecting the front wiring harness from the front module (located on the driver's side next to the air box). After disconnecting the harness from the ECM, leave the vehicle alone for a minute or so to allow a full reset. I personally turn the engine to reset all the sensors before hooking the ECM back up, however it isnt required. Reconnect the ECM and the vehicle should start. This is a short term fix until you can gather the money for a costly ECM unit. Good luck and I hope this helps.

you can test if the time is jumped, just move the distributor a little turning it to the left. and try to start. or change the rotor and the chip on your distributor.,......

or before that check your air intake box, may be the sensor that make open and close to controlled the air.


jumped time will be another option, . but i will be not %100 sure I need to revise the car my self to give u a exact cause,.

Is the timing belt still intact?

Sounds like a bad battery. Most auto parts stores offer free battery testing.

take it to a shop have them put a manual guage on it if it has low presure you need a new oil pump and new bearing but it is very bad to drive with bad presure

if its a 2.0L, the starter is on the side of the bell housing under the intake manifold.

It is very possible the "starter Solenoid" has failed within the starter. If this is the case the starter will do little or nothing. Also check connections at starter, lose cable? You should be able to jump across the starter to see if it works; if nothing then you know it is the starter. Oh yea, if it has an automatic tranny it may be the Neutral Saftey switch failed or out of adjustment; try wigglying around the gear shifter or try starting in neutral.

I hope this may have assisted you,
