My 89 plymouth reliant will just turn off while driving.some days it will turn off 5 or 6 times then it might run good for a couple of days.it keep fowling out the spark plugs.i have to clean them every 3 or 4 days and its using a lot of gas.When it does turn off it all ways starts back in 2 or 3 minutes.

SOURCE: 1985 Plymouth Reliant, spark to coil and plugs will not start, fuel goes to injectors

It has to be valve timing, so check the belt, it has jumped I bet

SOURCE: car shuts off after 2 miles of driving

It sounds like a clogged fuel filter

SOURCE: My 1988 Plymouth Reliant is starting.

THE TIMING BELT IS WORN AT THE CRANKSHAFT PULLEY.THE CRANKSHAFT WILL TURN THE ACCESSORIES BUT NOT THE CAMSHAFT OR TIMING BELT.

SOURCE: 89 reliant plymouth car stall out

You're right; It sounds like fuel delivery, but start with the simplest suspects first.
Change the fuel filter(s) first, and if this doesn't get it, go for the fuel pump.

SOURCE: 1989 Reliant K running poorly

my reliant (89) idles very high when you start it, then settles
down, but while driving it starts to chug very bad. I have new plugs, wires, distribitor cap and rotary button. How do I fix it??
